cursor offset on half the drawing area

when I use my wacom graphire the drawing and cursor only match on the right half of the drawing area. If I draw on the left half, the ink shows up onthe right half.

If I start onthe right half and draw to the left it matches up, but once i lift my pen the misalignment returns.

I read the thread below regarding a similar problem in which the cursor was always misaligned, but the solutions suggested (relative vs. absolute mode for example) don’t exist in my control panel.

Ideas?
