Why does IPhoto completely lock up my Intel Core Duo ? IPhoto seems to work OK until I try to edit a phot, then get visual artifacts on the screen and computer is completely locked up after 8 hours.
Snow Leopard 10.6.8 with IPhoto 9.2.3.
Create a new account (systempreferences -> accounts) make a new Library, import some shots and see if the problem is repeated there.
