Hi Dave, Your solution sort of defeats my intended purpose (sorry for not divulging my 'hidden agenda'). I wanted my application to "hide" the fact that it's a python script, and look as much as possible like it's a compiled program. The reason I don't just give my user a py file, is that I don't want a cleaver user to change the innards of the script. On the other hand, I don't want to make a compiled (freezed?) version of the application, because it'll grow the resulting file significantly, and I don't have the experience to know how it will run on different Linuxes. Bye, Ron. -- http://mail.python.org/mailman/listinfo/python-list
