Has anybody had this or heard of this problem w/ Leopard (or OS X in general)? My programs started randomly closing themselves starting a couple days ago. Safari, Adium and iTunes (the 3 I use the most) will just exit a lot of times it starts to beachball. I'm completely baffled by why it would do it; it didn't do it ever before. Tried repairing permissions/verifying disc...any more suggestions?
