Major Display Problem

I just purchased TBS6 and it does not work with my Cintiq. At all. Pushing buttons, drawing a line, anything, results in black screen or a scrambled display for about a half second. No problems with Photoshop or Corel Sketch Pad or anything else, only TB Studio.

The computer is an older Dell, but the display drivers etc. are up to date.
Nvidia GeForce 5200 FX, Windows XP. I hope someone knows what is causing this problem. TBS is completely unusable like this!

Try updating the tablet drivers and rebooting the computer. Make sure that TBS is running on the primary monitor if you have duel.
