try cleaning out your Settings folder to see if it resets the window position.
if you right click on an empty part of your taskbar, try Right Clicking and select "Cascade Windows" this should move them all to to the center, go though the stack and see if you find the correct one.I got the same problem. I click settings, and my taskbar shows the tab, but it isnt on my desktop, and there is no way to bring it up to the desktop (its not minimized, its just... not THERE, but windows 7 shows it as if it were minimized.)
