Hover Alert!!!
I think I may have found an answer. Try this: Start> Control Panel> System and Security> System> Advanced system settings (on the left side of the screen, Win7 Pro it is the last item). The Advance Tab should come up. In the performance section click settings. Check the “Custom” radio button. I disabled everything then one at a time started re-enabling them; so far so good.
I have hovered over everything I could find and nothing has happened that I did not want to happen. I’m going to test this for another hour before I post, just to be sure.
Well, I've done everything I could think of to make the darn thing engage while hovering. I really hope this works for you raebeia. I'm at gmail with this moniker if there are any questions.
