Thanks Apple. You fixed my iMac. It only took 20 days at the Apple store to figure out what was wrong. I’m still not sure what’s been fixed. Apparantly my logic board and video card were exchanged. Beyond that, the Apple voodoo spin machine won’t tell me much else. I’m happy that my comp no longer crashes when creating large gradients in Photoshop or visiting Flash websites. It’s like I’ve finally got a computer that does what it’s supposed to do. Wait a sec, I do!
