   // idea for multi-monitor systems.  Unfortunately, it appears to not work at
   // least some of the time (erroneously returning NULL) and there's almost no
   // online documentation or other sample code using it that suggests ways to
   // address this problem. We do the following:-
   // 1. Use the ABM_GETAUTOHIDEBAR message. If it works, i.e. returns a valid
   //    window we are done.
   // 2. If the ABM_GETAUTOHIDEBAR message does not work we query the auto hide
   //    state of the taskbar and then retrieve its position. That call returns
   //    the edge on which the taskbar is present. If it matches the edge we
   //    are looking for, we are done.
