Thanks for the info, Sheila! That's definitely an odd problem.
To start with, try downloading the following file:
Place the file in ArtRage's resources subfolder
e.g. c:\program files\ambient design\artrage 2\resources\ <-- put the file here
Then start up ArtRage. Does that fix the problem?
One note: If you hold the stylus just above the surface of the tablet and move it around, you should see the cursor following your movements. If you stop and place the stylus against the surface of the tablet, the pointer should remain in the same place. If you were to lift the stylus away from the tablet more than a couple of inches, then place it down somewhere else, the cursor should 'jump' over to the new location. This is becase the tablet can't track where the stylus is when the stylus isn't close to its surface. Check that this isn't what you're seeing there.
If that doersn't help, regarding the tablet driver, try downloading the latest driver software for your tablet from Wacom at www.wacom.com.
Before installing it:
1/ Go to Control Panel, Add or Remove Programs as 'Wacom Tablet' in the list usually. Clicking on that item, then 'Remove' will allow you to remove the Wacom tablet software. If you don't see it there
2/ Restart your computer
3/ Install the latest version of the tablet drivers via the file you downloaded from Wacom
Then see if that helps with the problem.
