I noticed that after I launch iPhoto, my system becomes incredibly sluggish, even after I quit the app. The system remains in this slowed down state until I restart. I don't think this was always the case... Anyone else have this problem? Is there some sort of background task iPhoto starts that it is somehow failing to kill on exit? Did I install something that conflicts with it and causes this to happen? I'm running 10.2.5 on a G4/466.
