[Visualpython-users] minimized display zaps VPython

[Bruce P. <bap...@te...>]

Under windows, when a VPython display window is minimized (using the window 
minimize button) and the un-minimized, when the window re-appears, all 
Vpython objects are gone. (no error messages, just no visuals)
First -- is this expected behavior? and what can be done about it. I can 
see how VPython may have difficulty updating a minimized window scene -- 
could smarts be added to freeze updating when the window is minimized? or 
alternately could window minimization be trapped so that full minimization 
is not allowed.
