Trying to show a progress bar...

Question

Helloo!
I'm having trouble getting my progress bar to update. I post the new control values, but it doesn't get a chance to redraw until either the End, or if I hit a breakpoint using ExtendScript Toolkit.
It DOES correctly disappear (close) at the end.
I'm setting a bunch of keyframes in a big loop. Takes a little time, nice to show the progress.
Oh, I'll show the code too. It's longish, sorry. Thanks for any advices!

Easy to use progress bar for ExtendScript.

return result;

As usual, thanks, that worked perfectly Jeff!
(I've gotten a midi-file parser working in ExtendScript, will post soon. Fun fact: adding a keyframe in AE is approximately very much slower than adding a point to a path in Illustrator. Illustrator is fast fast fast.)
