Hi, im a graphic artist and I was gonna use the tx2500 for sketching... i just noticed that after every few strokes or so, the pen stops being responsive, and I end up drawing dotted lines.. at worse, whole strokes dont come out. I use photoshop CS2 and Flash 8, and i noticed that even after I caliberate my pen, the cursor is still a bit off, it but only in these programs. On the desktop it would be fine. Actually it aligns perfectly if I use my left hand, but I use my right hand to draw... And near the edges of the screen, the pen tends to not be as accurate as it is in the center... Is it just me or is something wrong with my pen or did I get a lemon? any help pls?
