Progressbar on Mac AE CS3 & CS4

Question

Hey guys. Weird problem here. Seems Progressbar update in CS3 and CS4 (not sure about CS5) doesn't work properly on MAC. But I guess this is a known issues.
Any ways, I am building my progress bar window like this:
var PBWin = new Window ('palette', 'Progress Window', undefined);
var ProgressBar = PBWin.add('progressbar', undefined, 0, 100);
and later in my code in some for/loop I am incrementing ProgressBar values.
All works nice on CS6 and above, but cannot figure out how to make them work on CS3 and CS4. Any ideas?
I searched forum and found Update() option. But this only works for Window objects. However, if I change my "Palette" to "Window" that problem still appeas.
So is the a workaround with ProgressBars on MAC specific that work on CS3 and CS4?
From Peter Kahrel document scriptui-2-2.pdf if says:
Note: in scripts that use progress bars, you cannot set app.scriptPreferences.enableRedraw to false. If you do, the progress bar doesn't display correctly. This is on Macs only.
But that's irrelevant to AE, is it? Becouse it throws me an error when I try to add app.scriptPreferences.enableRedraw = true.

He didn't use Mocha, these clips aren't too recent...
Well, I know that the animated parts were done literally by hand, stop-motions, then saved as little transparent movies or animated gifs then loaded onto the filmed video..
So you think there isn't tracking really?? How could I make something pop up a book like this, when you look at it in slow motion, the animated shapes actually change perpectives and sort of disappear into the book... Does simple motion tracking tweek the "tracking object" as its tracking area interpolates??
Thanks
