  oWin:Refresh( <lErase> ) -> <lSuccess>

------------------------------------------------------------------------------

 PARAMETER:

  <lErase>     determines whether or not the background of client area 
               should be erased when the repainting of the window begins. 
               Default is TRUE, which erases the background


 DESCRIPTION:

  The ::Refresh() method sends a message to Windows that the client
  area of the window should be repainted ( InvalidateRect() ). 
  This may be necessary if some part of the client area are overwritten or 
  there are changes in the background of the client area. 
  If no parameters are passed, the background of the client area will
  be erased before the window is repainted.
