After some independent testing, I've found that turning on the 30 Bit Display option in Photoshop fixed the issue.
So, changing a setting in Photoshop fixed a Photoshop specific issue. Sounds like a Photoshop problem.
Ironic that you accused Wacom of "blowing me off" when they did actual testing before saying it was the program while you immediately claimed it was an issue with the tablet.
Between the non-existent support and the attitude, I am not happy.
