I keep hearing that Apple fixed the freezing issue with Leopard. However, I just upgraded my late 2006 white iMac 20" and it has froze-up on me about 12 times since Saturday. I have been able to download and install all updates that it detected.
Side issues, possibly related, are weird graphic events happening... an icon on the desktop went all pixelated; then a finder list was pink for 2 seconds... weird stuff.
Is there something I should download that was not part of the updates?
