I've noticed an insane little quirk in perl2exe - I have a program that launches another commandline binary indirectly through a module I didn't write. It works fine on my computer as a .pl script, and also as a .exe script, compiled with -gui or without.

On my boss's computer, it works when compiled to .exe, but only if I compile it without -gui. Exact same code, and it does run the rest of the program fine both ways, but for some reason on his computer it will not run the 3rd party binary unless that DOS window is present. Weird.
