I have a slight problem with window refreshing that I need some advice on.
I have a backdrop, simple_refresh window and then open a small, simple_refresh
window on top of it and immediately fill the smaller window with a 
BltBitMapRastPort() call.  Nothing happens.  If I pick up the small window
and move it, I get a refresh message and do another BltBitMapRastPort()
call.  This time it works.  In fact, I can't change the appearance of the
window unless I pick it up and move it (and get a refresh message).  That's
not quite true, since I can call drawing routines and the effect appears 
immediately; it seems that the fault lies with the combination of 
BltBitMapRastPort() and refresh messages.

Now the question: how do I get my bitmap displayed immediately on the opening
of the window?

Please e-mail me if you know the answer.
