Detect Browser Refresh - Related Problem

A related problem to detecting refresh is with the CNN web site. After my best efforts to detect refresh done, it continues (sometimes) to run a javascript periodically named prActivity (point roll - advertising software ). Once it starts (only if there's a flash add that must be calling the javascript internally - as point roll's doc says), then the IE ready state stays stuck at 1 until you navigate IE to a new web site - and we receive the document complete on the top document. This is with IE7 on XP home.

Is this a bug in IE7, or am I doing something wrong

My code is just waiting for and looking at status line change events and then tracing the IE Ready state. Stays stuck at 1 until IE is navigated to a new site.

Thanks.
