Comment 4 for bug 168819

I am having what sounds like a similar problem...

Vista (Home ultimate, or whatever theyre calling it these days)
Wacom Graphire 4

If the stylus moves out of range of the tablet (ie. too high) the mouse
pointer freezes.
The frozen pointer may be recovered by:
* Using the mouse
* Moving the stylus in at a low level from the edge of the tablet

This is also and issue with the latest version of GIMP (version 2.4.1)...
