Question:

When I run my Tk app from the command line: 
C:\playground>perl tk_app.pl

[download]
It works fine. After I create an .exe using PAR, it no longer works: 
C:\playground>pp -o hello.exe tk_app.pl
C:\playground>hello
...

[download]
It appears to be running. The command line does not return to a prompt. You can see it in the process table. The problem is there is no GUI. Nada.

Answer:

My firewall, ZoneAlarm, was silently preventing things from completely working. After adjusting the permissions for the application inside the firewall, everything worked as expected.

I know I have already answered my own question but I hope it helps someone else and this is the best section I think it fits in.

Cheers - L~R
