Someone knows why this happens?

A little searching would've found the solution for you. Most recent thread with the information: http://forums.themanaworld.org/viewtopi ... =6&t=10114.

I just had a windows (vista) reinstall yesterday on a computer.
I confirm this is a video card driver issue. Driver updates included in windows updates usually solve the problem. Otherwise, download the most recent driver as said Crush.
