Hi,
Using IE8 (or IE9 in IE8 Browser and Document mode) I get the following error when tweening background-position and calling reverse():
Invalid argument: TweenMax.min.js, line 15 character 58215
It seems specific to trying to tween the backgroundPosition in combination with using reverse().
I've created a JS Fiddle to reproduce the bug here: http://jsfiddle.net/ytKJq/4/
Any ideas how to get around this?
Thanks
Klas
