Storyboard & Device Drivers

I purchased Storyboard standard/ “for everyone” version (not Pro) via download on June 29 2007. It tends to crash a lot – often by drawing/erasing too many strokes too fast, or by selecting another panel to work on. I am now running it on a brand new Fujitsu Tablet PC with Windows xp Tablet – according to Microsoft it seems to be a “Problem caused by Device Driver”. Can you provide more info on how Storyboard interacts with Device drivers, and how to trobleshoot this? Thanks.
