Thanks for this info. I ended up installing the Wacom Bamboo pen and touch driver (before I got this message) and that seemed to re-activate the touchscreen...I think. Either that or it was the Recover App of Windows update that I ran.The touchscreen is working but the pen still has no sensitivity. I tried adjusting the settings in the Wacom Bamboo preferences but it gives me an error message that I don't have that particular Wacom tablet. Weird stuff. Could it be that the touchscreen tablet just doesn't have sensitivity for Photoshop? Or that I'm missing something in Photoshop settings? Sketchbook Pro's sensitivity seems to work fine. Why would Photoshop be any different?
I'm hesitant to uninstall stuff again as I don't want to lose the touch capability...
Thanks for your help. If you or anyone else has any more insight I'd appreciate it.
