my Adesso CyberTablet 8600 just started going wacky (the pen just starts moving[not shooting, just moving] off to the side). i haven't changed any settings whatsoever, system or software, and I'm using the same program I've always used (photoshop 7.0). i tried replacing the battery in the pen, but that didn't work, and i know its not because I'm shaky (I'm 17). the attachment shows what happens when i just set the pen down and don't move it. would like to get it fixed fast, have things to do before i go back to college, please help. P.S. if its a major hardware thing, break it to me gently. P.P.S. would defragging have messed it up?
