... I have to add that I am not dbl clicking any menu, file or link, rather, the pointer is just sitting over top of an item

I just purchased a new laptop with windows 7 and noticed that if I have my mouse pointer over a menu, file, link etc. it is either opened or closed depending on where my mouse is. To me this is a pretty annoying setting. Does anyone know how to turn it off?
