Closed July 21, 2011 06:43AM UTC decrementing loses scrollbar focus in IE

We have an app with an "overflow-x: auto;" enabled container, and are using a jQuery scrollevents plugin to simulate a 'scrollstop' event when the user stops scrolling for 300ms (even if not releasing the mouse button, but pausing in mid-scroll for 300ms)... When scrollstop fires, it's supposed to ajax-load content in the visible containers in the scrollable window, and this all works fine...

However, in IE *only* (version 7 as far as I can tell, not sure about 8), when those ajax requests fire, and the done function executes, and this specific line executes near the bottom of that function (line 7148 of 1.6.1):

if ( !( ) ) {

The act of decrementing that variable seems to cause IE to lose the user's grip on the scrollbar handle, they have to re-click on it to continue dragging back and forth... I've tried separating the math from the logic check by decrementing it first and then checking the value (with the decrement operator in front of and behind the variable). I've tried scrapping the decrement operator altogether and making = - 1. I've tried changing the reference to jQuery['active']. I've also tried something like this:

temp = - 1; = temp;

In all cases, it seems that anytime that 'active' property is decremented, the browser has a brain fart and loses its focus on the scrollbar... Incrementing that value does not cause the problem, but causes that if-statement to never evaluate to true and never trigger ajaxStop... I also tried adding an activeTotal variable that I could increment as ajax requests completed, and just compare that == jQuery.activeTotal, but the *incrementing* of the activeTotal variable caused this issue to happen also... I'm at my wit's end on why this would be happening... Help me Obi-Wan Kenobi's, you're my own hopes...
