Progress Bar Never 100%

Question

Ok, kind of an odd issue, but I've got a script that can take a considerable amount of time to run due to all the sub-scripts.  Anyway, I've setup a progress bar to work with it so I can tell how far it is.  The only problem is, unless there is an alert or something that pauses the script (like a pop-up), the bar NEVER shows 100% full; even if I use an in-script pause such as the sleep command.  Any ideas how to fix this?  An example script is below and also never reaches 100% filled bar.
#target photoshop
var list = ["one", "two", "three", "four", "five", "six"];
var w = new Window ("palette");
var progress = progress_bar (w, list.length);
for (var i = 0; i < list.length; i++) {
    progress.value = i+1;
    // user functions
    $.sleep (400);
progress.parent.close();
function progress_bar (w, stop) {
    var pbar = w.add ("progressbar", undefined, 1, stop);
    pbar.preferredSize = [300,20];
    w.show ();
    return pbar;
I've also tried adding "w.show();" immediately after the "progress.value = i+1;" and still nothing; but like I said, if an alert pauses the script, it will work right.  Any ideas?
Thanks for any help!

Lol, ok, now I feel stupid.  I actually found the fix for the issue on my own.  To fix it, simply replace the $.sleep(400); with w.update(); (the sleep is pointless and pretty much just slows down your script).
