Badly designed UpdatePanel may cause this issue in the popup IE page. For example, you have UpdatePanel in the start of the page. Then have a window.close button inside this UpdatePanel. Just close and open this 2 or 3 times from base IE. After that it hangs.
Resolution:
1. close button should not post back, so you can have return false in OnClientClick event
2. close button should be outside of update panel
3. call Sys.WebForms.PageRequestManager.getInstance().abortPostBack() on body unload
