Bug on drawing (need help!!!)

i have installed toon boom studio 6 on my laptop, a hp with windows vista, and most features are working well apart from one. in drawing mode whenever i try to draw with mouse or tablet the screen goes black untill i stop drawing. please help if u know what to do or have experienced this.

Looks like a Graphic Card issue…?
In Toon Boom Studio’s Preferences / Display…
Change from OpenGL to Quartz2D/Direct3D or vice versa…
Restart Toon Boom Studio.

Nolan

That usually fixes it… but if not, please post your graphic card model.
