I had a requirement recently of using the jQuery.animate method and i was animating the left attribute of a div. Some thing like this.
$(“parentdiv”).stop().animate({“left”: (-($(“childdiv”).position().left))} , animSpeed, easeType);
it worked fine till some negative values like -10000 and after that it was acting weird running here and there. I googled a lot for this problem and there are a lot of post on the internet, one of them which says set the position of the animating div to relative or absolute or fixed. i tried all that but it didnt work. I was going nuts and untill i found a post which said that this was a bug in jQuery 1.3 and was fixed in later release, But anyways i was using jQuery 1.4. but that was great hint!
So anyways the Solution to this problem is upgrade to the latest version of jQuery as it contains all the bug fixes. So i am now using jQuery 1.7.2 (latest at this point) and it works like a charm in all browsers.

Can you point me to the other resources referencing this problem that you found?
right,
here is one http://stackoverflow.com/questions/7455831/jquery-animate-and-google-chrome-issues this one says try appending “px” at the end of the left values in the animate function.
then here is another one http://stackoverflow.com/questions/481288/jquery-animate-issues which says try using “border-something” or “margin-something” instead of left.
both of these didn’t serve my purpose… but fine upgrade works for me.
