Installing
and Using the Lettus Application
The Lettus Application can now be run through an Internet Browser such as
Microsoft Internet Explorer. To get started
using Lettus through a Browser, click on any of the links below.
1. What is Lettus?
Lettus is the name of the Fresh System Application. Previously this application was run through a terminal emulation software called “Smarterm”. Lettus can now be run through an Internet
browser such as Internet Explorer. This
is sometimes referred to as “Lettus – GUI” (Graphical User Interface).

2. What is JInitiator
and why do I need it?
On Windows PC’s, Lettus uses Oracle JInitiator to access forms through a web browser such as
Netscape or Internet Explorer. Lettus
screens will not run on the client machine unless JInitiator
has been successfully installed. JInitiator is not required for Macintosh Computers.
Jinitiator
is a Java Virtual Machine (JVM) that plugs into either Netscape Communicator or
Microsoft Internet Explorer to replace the native Java Virtual Machines that
those browsers provide. Jinitiator provides a newer JVM version than the one
shipped with these Browsers and a JVM designed specification for the running
this type of application.

3. What to expect when downloading and
installing JInitiator
For the first-time user of Lettus (or the first time running Lettus on a PC or laptop), this *one time only* step is required. This is what to expect:
Troubleshooting
If you
encounter the message : “unInstaller setup failed to initialize. You
may not be able to uninstall this product.“ then you may not have permissions
to install software on you PC or laptop.
Please login as an Administrator user or contact you IT support.
4.
Installing Adobe Acrobat Reader version 7.0
To view reports on the screen, you will need to install the latest version of Adobe Acrobat Reader. By default, reports are displayed to the screen in PDF format. These can only be displayed using Adobe Acrobat Reader. Adobe Acrobat Reader 7.0 can be downloaded from the home page (or click here) of your server or at http://www.adobe.com/products/acrobat/readstep2.html. When downloading from the Adobe site, you can de-select the “Adobe Yahoo! Toolbar” and the “Adobe Photoshop® Album 2.0 Starter Edition” check boxes. This will reduce the size of the download.
Only version 7.0 and above of Adobe Acrobat is supported by Fresh Computer System. Adobe Acrobat Reader is free.

6. Allowing Pop-ups
from your Lettus Server?
You will need to allow popup windows to appear from you Lettus Server. To enable Popups,
go to Internet Explorer and select the “Tools” -> “Internet Options” from
the menu. Select the “Privacy” Tab and
Click “Settings” in the Popup-Blocker Section.

Enter the
address of your Lettus server here and Click “Add”.

Alternatively,
you can disable the pop-up block by de-selecting the “Block Pop-ups” Checkbox.
Pop-up
Windows are typically used by websites for advertising. By default, Internet Explorer will block most
pop-up to prevent those annoying adds from
displaying. Lettus displays reports by
using these pop-up windows so you must ensure Pop-ups are not blocked for the
Lettus Server. If so, nothing will
happen when you try to run a report to the screen.
If you have
followed the steps above and still do not see anything when running reports to
the screen, you may have another Pop-up blocker installed on your PC. These can be a part of Internet Explorer
Toolbars (like the MSN Toolbar) or part of your Anti-virus / Spyware Software such as Norton Anti-virus or Norton
Internet Security. You may need to check
these programs for similar Pop-up Blocker options and disable the Pop-up
Blocker or permit Pop-ups from your Lettus Server.
You may also wish to read this document to assist you in diagnosing how to disable other common Popup Blockers
7. Running Lettus for the first time
Once you have successfully installed JInitiator, you can run Lettus. The first time Lettus is run, it will
automatically download a number of files and store them on your computer. This will happen automatically but it may take
quite a long time. Once these have all
been downloaded, they will not need to be re-downloaded again. This initial downloading of these files may
take up to 10 minutes over a broadband connection and much longer over a
dial-up connection. Please be patient.
While these
file are downloading, the browser may appear to be not responding. You may notice the status bar at the bottom
of the browser indicating that it is downloading …/f90all_jinit.jar (or
similar). Please be patient and allow
these initialisation files to download.
8. What is my Username and Password?
If your Application has been moved to GUI from the Character based (Smarterm) version, your “Login” will be your first login,
probably your name. In the Character
mode version, you would have entered this initially at a unix
“Login : “ prompt which probably looked something like
this:

The new
Browser Based environment will require a password on this account. You may not have had a password at this level
before. Please check with your System
Administrator for your new password. You
will probably be forced to change your password the first time you login.
You may
also need to enter a Security ID and
password. The Security ID determines the
access permissions you have within the Lettus Application. Your System Administrator will determine
wether you are required to select a Security ID or wether one is assigned to
you automatically.

10. How to avoid losing your
Lettus session if you click on another web link inside of email
You will need to set an option in your IE browser configuration so that any new web link will be created in another, new IE browser window. To do this:

11. What about Macintosh computers?
Macintosh computers can be used with
Lettus however they may require some additional Configuration on your
server. Please contact Fresh Computer
Systems if you would like to run Lettus on a Macintosh. The Macintosh must be running Mac OS X
version 10 or above. The Internet
Explorer or Safari Browser is supported on a Mac.
Not in the initial version of Lettus. This version of Lettus is a migration from the character mode version and cannot yet support a mouse (expect in the Menu and some screens). We will be gradually enabling the Mouse in some screens as we re-write parts of the system for this graphical environment.
13. Optimal desktop display settings for
Lettus
The Lettus Application will run at optimal size when your PC screen is set at 1024x768 screen resolution with your Windows “Taskbar” at the bottom of the screen (default location). We recommend you run Lettus on a 17-inch Monitor or larger. Lettus will NOT display correctly when running in 800x600.
The following notes describes how to set you screen to 1024x768:
Note: If you are using a Widescreen
laptop and Lettus looks strange and untidy, see the troubleshooting section
below.

NOTE:
Always close all unused and inactive windows to ensure the best overall
performance. If you need to run other programs that are not on the
list, be sure to close some of your unused applications. The Browser Based version of Lettus (GUI)
requires more processing power on your PC than the old Character based
version (using Smarterm). An older PC will run slower than a new PC. |

Cannot start GUI: …main.class Not Found or GUI hangs when launching with …main.class in the status bar.
You may be
running through a proxy server. You will
need to bypass the proxy server to access Lettus.
Lettus looks strange and untidy.
Text is larger than normal and fields may be smaller. Some headings do not align with their
fields. Click
here for an example of this problem.
Check your display settings. Some widescreen laptop will run at a high
resolution and use a lager DPI setting so text in webpage’s and documents
appears larger. This disrupts the layout
settings in GUI. To change the DPI
setting back to 96 DPI:
