RAWR! This thing won't calibrate! Well, it will, but incorrectly. :P
I did have it calibrated fairly well, but in the middle of a drawing (at some point, anyway), it started to shift. I started noticing my marks were off and lo and behold, the cursor's off!
I try to recalibrate... and keeps. Getting. A little. Off. Rawr!
Any tips? :p
You should know I do have a ViewGuard sheet over it, so... dunno about that. Maybe I should take it off, but... scratches! ><
