I think this may be the answer as i'm not fully
understanding the way windows are. But, right click on
the toolbar and click undo cascade or the might say undo
tile windows or something you should click on that, it
shloud fix the problem.
Open one IE window only. Resize it with your mouse so that it is almost
full screen. (You could use the Resize command in the taskbar button's
right click menu to do this instead.) Then press Ctrl and click X to close
the window.
