My IE9 windows are becoming confused, and I find that 2 menu bars are displayed, but only the lower bar works. There is a gap between the two bars, and in that gap you can see other menus (eg on the Google page it shows their menu for Web, Images ...). The problem is that you cannot get to the top of the "page" as it lies up underneath the confused set of menu bars (see image).
