I am seeing very slow behavior in IE8. It seems to happen on a mouse click, and it seems to be related to the size of the page. The more content on the page, the longer the delay is.

I've attached a screenshot of an IE8 profiler report.

Unfortunately the Javascript code is obfuscated, but I am positive that it is jQuery. I've also attached the code snippet that I think is causing the problem.

Can anyone tell me what exactly the function "bK" is, and why is it being called? It seems to be called on every mouse click. Is there a way to work around this?

I do not see this problem in newer versions of IE.

Thanks.
