My computer was already set to double click so the adjustment in Folder Options did not help and I was still experiencing all kinds of things opening and moving because of the mouse hovering. I also didn't use the solution for the submenus since I actually like to have submenus open if I hover as I often use that for drop and drag and that still didn't seem to be a solution to the additional hover items that are affected in Windows 7 as compared to Vista. Many more things opened or expanded without my wanting them in this format. I have not been able to find anything from Microsoft saying how to disengage The most helpful was when l I tried a partial of Damocles 13's solution pasted here " 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 did not disable everything, only the "animation" options and without spending a lot of time, this seems to have done the trick. If I have some time, I may also see if there are one or two of these that could remain on as now if I scroll over programs open, it doesn't show a preview of the open items, just a text version. However, that's much better than a pile of things moving expanding and opening without "request". It would also be really much more helpful if there were descriptions of what each option does so that one could make an intelligent decision about whether one wishes an option or not.
I truly hope this saves someone the hours I have spent and the opportunity not to be "too aggravated".
