For a while, my XP (SP3) has had an odd issue. On occasion (I'd say between 10-25% of the time), I cannot shut down my XP without first ending the program DritekECWnd.exe. I cannot find the file via search, and Avast! isn't picking up anything. I searched the registry and deleted an entry by that name. For a while, things seemed to work, but now the problem has returned. What is this file? I cannot find out anything on it through Google or other search engines, and I can't find it on my computer.
EDIT: I cannot find the process in the Task Manager either.
