With so many top shelf artists working exclusively on Mac OS X I have no idea why Wacom consistently puts out such horrible software to negatively complement their hardware. Then again the drivers could be just as terrible on the Win side, but I'd sell my soul before ever finding out firsthand.

FYI - Release candidate:

The term release candidate (RC) refers to a version with potential to be a final product, ready to release unless fatal bugs emerge. In this stage of product stabilization (read QA cycle), all product features have been designed, coded and tested through one or more Beta cycles with no known showstopper-class bug.
