I got a second monitor for Christmas and when ever I plug it in Cataylst eventually crashes. i first thought that it was dude to and old driver version so I downloaded 9.12, this did not help. I'm running both screens at native resolution and refresh rate. The card is a Sapphire 4850. The monitors are different resolutions. The main is running direct DVI the new one is running to VGA. I am running Vista 64.
