Pingus hangs when full screen on MacBook Pro

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Went into Pingus preferences and changed some, including Full Screen
2. Now when I open Pingus the screen flashes black then back to what was there 
before except that I have the Pingus menu bar at the top of the screen (Pingus  
Window) but no Pingus window.
3. I have tried to delete Pingus and reinstall it but the problem is still the 
same - presumably the settings are still stored.
4. So now I can't get back in to change the preferences back!  I would 
appreciate knowing how to delete the stored preferences.
Thanks
Charlie
