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 <BODY> HTML tag.

Resolution

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
