Animated gif does not animate on page load in IE

I have a resource intensive ASP.NET page. I have a div element with an image that I set the visibi开发者_Python百科lity for before and the after the page loads. This fails in IE. IE stops animating the image.

I have tried all possible solutions that were presented in different message boards with no luck.

Any help is really appreciated.

My guess is your are using an UpdatePanel and IE is pegged trying to parse the DOM. See this article for KB 2000262 - Fix: UpdatePanel Async Postbacks Slow in Internet Explorer. Check your task manager when this happens and see if IExplore.exe is %100.
