Full disclaimer, I use a aiptek drawing tablet. I am running vista I have two processes of wisptis.exe in task manager. One has a description the other does not (blank) the one with a description refuses to end and the one without claims that it cannot end the process (access is denied). This even occurs in safe mode. wisptis does not appear in services. what am I missing? It's just really annoying, I am relatively certain that it is the culprit behind my mouse going haywire intermittently.
