Weird shortcut messup

[Christiaan Hofman]

On my system I'm having some very weird shortcut messup. When I hit  
Option-Command-P, the action bound to Command-, (Command-Comma) is  
activated (usually showing the preferences panel). However this only  
happens after I have hit a few unmodified character keys. I can  
reproduce it with every Cocoa app on my system that has a Cmd-,  
shortcut. I've tried to turn off every deamon, APE, input manager I  
could find and re-login, without success. I'm completely lost. If  
anyone on this list could tell me what could cause this, I would be  
very grateful.

Thanks,
Christiaan
