I've had problems with an unstable system for quite some time now, since I messed around with the system quite abit since I bought my PB, I decided to reinstall everything from scatch. So the only progs running in the background are: Launchbar 4 Palm Desktop background and Transport Monitor (newest versions) Calenderclock 1.0 Microsoft AU Deamon (Office 2004, updated) iCalAlarmScheduler (don't know if that was installed by me?) Anyway, my system is still unstable, which means I had iTunes, iPhoto, Firefox and Bittorrent crash several times in the last 2 weeks, and I had 1 major crash of the system (while using Firefox, suddenly the screen turned grey saying that I'll have to reboot my system). Anyone know what that could be? Is maybe one of my programs running in the background known to make Osx unstable? ANother thing that could be of importance is that I was always using my airport express when something crashed (firefox, bittorrent->internet, iTunes->streaming music, iPhoto->print). Could maybe the airport express crash applications?? Thanks a lot for your help!
