iPhone Simulator Black Screen

Hi, whenever I launch the iPhone Simulator just from my Applications folder I get a black screen, same happens when I change hardware and software versions of iOS. I'm running Xcode 3.2.4 and trying it from a clean install. When I try to build an app from Xcode the simulator launches in iPhone mode and just beechballs. with the same black screen.

I'm getting some stuff in the console, not sure what it all means but here it is..

I'm running an intel iMac on 10.6.4. There's also other people in the office having the exact same problems so I know it's not just my computer.

Ever happened to anyone before? Is thre a quick fix?

Thank
