I have a perfectly good Bamboo fun (Cte-450) that about 95% of the time doesn't work. Anyone have any tips for me? It randomly stops work and only a restart will fix the drivers so it will keep work. Not to mention I just can't plum draw in adobe with it. Sai is apparently the only program lite enough that I don't get jagged lines. I've always had this problem with it, but lately it's just chosen to not work at all. http://puu.sh/5WkOB.jpg <--- is the error I get.
