This will make the fullscreened windows floating, which leads to the same  
problem as the OP had, with multiple fullscreen windows overlapping and no  
easy way to switch between them.

With the XMonad.Layout.Fullscreen solution, the windows are kept in the  
tiling layer, making them easy to switch between while still taking up the  
entire screen.
