Solved Drop-Down menus won't stay open

[parnless]

Any time I try to open a drop-down menu it open for about a second and before I can move my cursor to click on anything the drop-down menu closes. I had this problem before and I was instructed to delete a specific line in the Registry. It totally solved my problem, but I can't remember how to do this. Any help would be greatly appreciated.

Found the solution. I just unplugged my wireless mouse, waited 10 seconds, then plugged it back into the usb plug and it fixed the problem. Much easier than fooling with the registry.

DUDE! Thank you so very much!!! This has happened to me on two different occasions over the last year and I ended up formatting both times. I never thought the fix would have been this easy!

Again, thanks a TON!!
