Justin,

I was able to replicate the problem using "python", and confirm proper  
working with "pythonw". However, when previously running the app  
manually, I was using the startup command string as found in the  
VenueClient's log file (effectively using "pythonw"); this worked  
perfectly. Yet the same startup string when used by the VenueClient  
itself caused problems. ???

I rewrote one of the apps in a "nicer" style (less inheritance  
trickery) and its working now (on all of OSX, Linux, Windows), so I  
guess I'll just have to redo them all.
