Everytime i try drawing on my tablet it glitches horribly. Whenever i put the pen tip to the tablet the cursor completely spazzes so it's impossible for me to draw anything. It goes away occasionally but afterwards comes back and happens to be even worse. I tried just unplugging the tablet usb and letting it sit for awhile but even after that it would only cooperate for a few minutes. Any ideas?
