Hi
If your O.S. is Vista, maybe you have a problem ...
With a Nvidia GPU, I had the same issue running SB Pro Pe on Vista (32 bit): even with the latest and certified drivers, the only way to run it perfectly was the windowed mode ...
Now, I came back to XP and everything (not only SB Pro ) runs fine and flawlessly.
If you have an Ati GPU, maybe you can solve the problem with the latest Catalyst, as suggested by JamesT73J.
