I don't know your exact code, but I'd rearrange the loop so that
SDL_PumpEvents() is at the very end of the loop.

Simpler example below, for reading input in from a file:

--Instead of this:
atom fn
object line
sequence text
text = {}
fn = open("myfile", "r")
line = {}
while sequence(line) do
	line = gets(fn)
	if sequence(line) then
		text &= line
	end if
end while
close(fn)	
--end--

--Try and write it like this:
atom fn
object line
sequence text
text = {}
fn = open("myfile", "r")
line = gets(fn)
while sequence(line) do
	text &= line
	line = gets(fn)
end while
close(fn)
--end--

Pete! Thanks so much!

After I sent that last post, I realized that my loop should probably be more
controlled... that I really didn't have a hook into it (like you did with
the done variable). However, didn't know where to go with it so I'm glad you
responded.

How would you resolve this, however: the loop uses done, but then it exits
if done is true inside the actual looping code. What I'm thinking is that it
can be optimized or done differently so there aren't two tests for done in
the same loop code.

while done=0 do -- here's done
   SDL_PumpEvents()
   if done then exit end if -- here's done


Again, much appreciated!

change:
setHandler( bttn_Close, w32HClick, routine_id("PushButton2_onClick"))
to:
setHandler( bttn_Close, w32HClick, routine_id("bttn_Close_onClick"))

at the end of sdl_done() I added:
done=1

and also put an extra exit line in the main loop as follows:

while done=0 do
SDL_PumpEvents()
if done then exit end if --<< here
