SYMPTOMS
When you view a Web page in Microsoft Internet Explorer 6 Service Pack 1 that uses absolute positioning together with dynamic HTML (DHTML) element behaviors, you may notice that the memory for the Iexplore.exe process increases at a fast rate until the computer stops responding (hangs) and CPU utilization for Internet Explorer may remain high for a long time.



CAUSE
This problem occurs when Internet Explorer displays absolute positioned elements on a Web page and processes a DTHML element behavior on the  HTML tag.



RESOLUTION
