I've got a problem with my pen tool: the front end doesn't work, and whenever I use it and pull it up above the tablet, it still thinks I'm pressing it and keeps drawing a long line. I've been forced to let it draw a line between what I was drawing and what I will be drawing, lift it completely out of range, and then ctrl+z, draw, and repeat. does anyone know what I could do (short of buying a new one, they cost 30 bucks, and I'm cheap.) to stop it from being so stupid? I mean, the way it is I can't even use the software.
