Thanks Ken,

I made the cosmetic changes in subroutine calls. Added strict & warnings, and fixed 'explicit package names' warnings. No change in outcome.

I did not replace the destructor with 'exit' or remove the commands after mainloop, since the whole point it to be able to continue the program after mainloop exits. The problem is that it doesn't exit.

I do not understand the problem with having code after mainloop exits - 'normal' or not. Everything I know tells me the program is not required to end when the GUI does, anymore that it needs to end after a print statement.

I'm still clueless.
