Hey Moose,
Did you ever get this problem with your tablet resolved? I haven't figured mine out yet.

Thanks!
Kevin

Hi Kevin, the only thing I can really think of is to try a different driver.

It looks like there are 5 different driver versions available for your tablet here:
http://www.wacom.com/productsupport/drivers.cfm?os=XP&product=CTE4

The newest one there actually says "RC" which means Release Candidate, that means it is still kind of in progress and hasn't been completely finalized. Maybe that one is not a good one to use, maybe try one of the older ones.

Also you might try uninstalling your current driver using Control Panel / Add or Remove Programs before installing any older version.
