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 problem . .there’s a lot of JS on that page. Checking by hand is not a good ideea

EDIT : It’s a page from a project i’m working on… but I need a tool to find the problem.

End : It turned out to be the UpdatePanel – somehow it would get ‘confused’ and would take too long to process something. I just threw it out the window – will only use JQuery from now on :D.

And I’m selecting Remy Sharp’s answere because I really didn’t know about the tool and it seems pretty cool.

  1. Get yourself a copy of the IBM Page Profiler:

    https://www.ibm.com/developerworks/community/groups/service/html/communityview?communityUuid=61d74777-1701-4014-bfc0-96067ed50156

    It’s free (always a win). Start it up in the background, give it a few seconds, then refresh the page in IE. Go back to the profiler and it will list out all the resources used on the page and give you detailed profile information – in particular where JavaScript is taking a long time to execute.

    It should be a good start to finding the source of your problem.

    If the script tags are inline, I’d suggest creating a local copy of the file and separating out the script tags to separate files if you can.
