I asked how to pass redraw messages to applications whose windows I had 
scribbled in.  Hedley Rainnie posted a piece of code that handled dialog
closing properly, and Greg Anderson explained it.  In summary, GEM doesn't
know about the scribbling, but the correct form_dial() call tells GEM to
send redraw messages.  I looked at my code, and the problem was that I
ended the dialog handler with form_dial(FMD_FINISH, cx, cy, cw, ch, 0,
0, 0, 0);.  Apparently this only sends a redraw to a null rectangle 
rather than the one defined by cx cy cw ch.  The fix is then apparent.  
It appears from the documentation I have that DR defined this call as
taking only one rectangle as an argument, but wrote the code to require 
two.  As a result, the documentation available is not quite clear enough to
penetrate the cotton in my head.  (By the way, I use MWC).
