Questions:

* What happens when you click on the launcher stack? Does it disappear and
then nothing happens?

* Is "admin" the name of the main stack that is stored in your app.rev stack
file in memory?

To start troubleshooting this you can add a breakpoint to the
glxapp_openApplication handler in the application stack script. This is the
handler that opens the stack targeted by kProgramStackName. When you get to
the breakpoint you can refresh the list of stacks in the Application Browser
(little refresh button at the bottom of the left column in the Application
Browser) and verify that you have a stack in memory whose name matches the
value of kProgramStackName.

If you aren't familiar with using the debugger then you could add the
following line to the glxapp_openApplication handler:

answer there is a stack kProgramStackName

This lesson explains what each .dat file does.
