Never ever, ever, test anything for distribution inside an IDE!
Always test it as it will be run - from the OS prompt or filemanager.

IDEs can introduce subtle differences of behaviour that conceal bugs.

Similarly never ever do a final test with debuggng code switched 
on or the debugger active, again the debugger can cause subtle 
changes in behaviour.

Do you run it with python or pythonw, that might also make a difference.
