I am getting really frustrated. I have a new-ish Wacom Table, one of the smaller ones. And just in the past few days the pen has been malfunctioning. I'll be drawing lines, and suddenly the pen will just stop on the screen. The only way to get it going again is to click the mouse and it scribbles all over the screen, forcing me to go back several times to reach the starting point.

Has anyone encountered this? If so, How can I stop it? I can't draw for more than an hour before I just want to give up. It's so friggin' annoying and interrupts the whole flow of the drawing session.
