Same problem here. Dell mini 9, XP sp3. It just started doing this, when I bring it out of hibernation, I get a "ObjectDock has encountered a problem and needs to close" message. I have to then start it through the task manager and it works fine. Very frustrating. Has anyone figured this out yet?
UPDATE: I think the problem is with DEP and Windows Explorer. I turned DEP off for this windows app and it seems to have solved the problem.
