I upgraded my Mac from 10.4.3 to 10.4.4 (with Automatic Updates) and the same day purchased and installed the iLife 6.0 package (that updated the 5.x version that came with my Mac).
A day or 2 later I decided to change the background photos on my displays. I had been using photos from my iPhoto library and as I scrolled around looking for appropriate pictures and trying them out System Preferences quit on me. I had to restart in order to bring back the ability to alter the background images. Other programs and operations remained unaffected. iPhoto was not running at the time.
These problems never occurred with 10.4.3 or before or iPhoto 5 or before. I don't know if the problem is with iPhoto or not, but I assume that there is interaction between System Preferences and iPhoto, or at least that System Preferences uses the iPhoto database files.
Any ideas?
TIA!
