window display clearing display first

[JDHorn@xxxxxxxxxxxxxx]

   I have an issue with a window clearing the display
    
   old oe system calls window1
    
   window1  requests fax info
     calls window2 to find customer fax numbers
         returns to window1 with lr on
     calls window3 to display error message
         when window3 displays, it first clears the display
     
   if I return from window3 and call another window program the display is
   still cleared.
        
   the background will not return until window1 is redisplayed
    
   if window2 does not turn on LR, everything works just fine.
    
   all of the display files have records with assume and keep keywords in
   them.
    
   all the record formats displayed use the overlay keyword.
    
   I tested this in a number of different ways and it seems to be a universal
   truth.
    
   Is this normal behavior?  Is there a way to make this work with LR on?
