The problem is in the title - IE is misbehaving and is saying that there is a script running slowly - FF and Chrome don\'t have this problem.
How can I find the prob
@nikmd23 answer is informative..
My 2 cents here... I had the script warning issue - due to loading a dropdown list items with the help of for loop.
I referred @Eric Leschinski post in Disabling the long-running-script message in Internet Explorer.
Refer setTimeout for loading items in a dropdown list to see how I resolved this problem
