Hi Pierre,
I'm not sure if this means anything to you, but I found that if I set
'AlwaysSetDeferUpdateTimer=1' then outline boxes are partially drawn and
damaged regions are sometimes partially redrawn. The location and extent
to which the lines are drawn is seemingly random, but it's never complete
(except when a screen refresh is requested). Also, the value of
'DeferUpdate' does not seem to make any difference. Any thoughts?
Thanks,
