I'm getting the following error when trying to run Tweenlite in IE7 and IE8. I have no troubles with the animations I'm running in grade A browsers as well as IE9.
I'm using tweenlite and the cssplugin. I imagine it has something to do with the properties I'm using for animation.
SCRIPT87: Invalid argument.
[url="0"]TweenLite.min.js, line 44 character 35[/url]
Here is a sample of how I'm using tweenlite:
TweenLite.to( $(tabber), 1, {css:{left: 0}, ease:Expo.easeOut});
TweenLite.to($self,useSpeed,{css:{backgroundPosition:coords},ease:Cubic.easeOut});
