[AccessD] Screen Flutter

Dear List:
 
Legacy app.  Continuous bound form with no sub-forms.  When it opens it
'flutters' I guess what we always call here the 'flashing screen'
phenomenon.
 
It flashes or flutters 3-5 times during opening.  There are a bunch of
requeries and a couple of repaints in the code but that's not causing it
because I comment them out one at a time and saw no change.  
 
Tried Me.Visible=false on entering the open event and Me.Visible=True before
leaving the open event.  No difference.
 
So what's the most likely cause of the fluttering or flashing on open?
