Blackberry simulator screen refresh

When I use the stock Blackberry simulator, the screen seems to NOT repaint when I interact with the virtual 开发者_运维知识库device. I have to minimize/restore the simulator app for the screen to get repainted, but it should have repainted on its own.

This only happens on my Windows 7 machine, any ideas?

in the simulator disable graphics acceleration

menu view-> graphics accelleration -> off.

this does the trick.
