I hope this doesn't create extra unneeded picture objects in memory,
so I can perform code like:

   DIM Pic AS Picture
   Pic = MenuCustomColor.Picture
   Pic.Fill(Dialog.Color)
   MenuCustomColor.Picture = Pic

for any number of times without memory penalties.

Please confirm this.

Thank you,
David
