lHey Ive managed to make the calibration work with the wacom drivers
Unfortunately both upper left and right corners are still causing the cursor to jump like crazy. Off by 5mm +-, still bloody impossible to hit toolbar buttons on photoshop haha.
Also, why would I calibrate with the stock wacom utility again after that 100+ points power calibration? You said it might be good but in which cases? And why would it not overwrite or mess with the first calibration?
You are right, you need to do the stock calibration. That's why I said I backed up both registry and .dat file, which contains data about the stock calibration. It won't harm the 100 points calibration, don't worry. However, my upper left corner accuracy is not that good. My habit is put taskbar in the left side of the screen, to get the screen become somewhat 16:10. I think you can try it.
