I am having an issue trying to do anything. I click on a tool, the screen pops up in the middle but then when I move my mouse over to that screen, the drop down menus all pull down in a large black screen so that I cannot get to anything. The screen also does not go away if I try to click away from it, but only if I choose one of the options from the list. I would click analyze data which would take back to where I started. This happens for every tool that I try. I did not have this problem this morning or afternoon, but I've been trying to get it to work for almost an hour. As soon as my mouse hits that center area (top, bottom, middle), the screen comes down, but only after I select a tool. Please help.
