I am using update progess to show the animated gif saying "Loading..". I am testing in IE 8 and the animation freezes.
I have come to know that IE 6 & 8 have a bug to handle this and have found certain supportive links such as here and here as well, but i'm not sure how to apply in update progress to resolve my issue?
Please help!
Thanks!
When this happened to me, the browser's processor was actually pegging out due to KB 2000262, there is a fix, if this is your problem:
