Sorry to start 2 new threads in a row, but this is completely seperate issue which needs its own conversation. I've been force quitting the process "ISDtouchuser.exe" when I am only using the pen, because I was finding it causing glitches and wonkiness when using the pen, even when touch was disabled. But now, I am finding if I try to leave it on as I draw, the problems start to become more and more frequent as though the system is getting laggy, and progressively corrupting or something. So then I'll go to shut it off and see that it is taking upwards of 500,000 K of memory (private working set) !!! That's clearly a bad driver, and I wonder if it's a result of fighting with other drivers on here, and if you guys have been having issues with this driver as well? I know it came out fairly recently, so maybe some of you haven't begun using it yet. So do me a favor, next time your drawing, open task manager and have a look a the process and see what kind of a system hog its being, and let us know if it is creating random twitches in your digitizer experience. I am considering calling Wacom if there is more people than just me experiencing this issue with their newest tabletPC driver. thanks!
