"Operation aborted" error constantly on IE8

Just upgraded to IE8, and now I'm constantly getting the following error:

Windows Internet Explorer
Internet Explorer cannot open the Internet site http://...
Operation aborted

Sometimes the page disappears when I click OK, sometimes its still there.

Is this a known issue for IE8?

Solution 1:

Actually it was a known issue even before, although the IE team claimed to have fixed it. Basically that message meant that the page was trying to manipulate its DOM tree while not fully loaded. Something where the specification says that behaviour is undefined.

They also link to a Knowledge Base Article.

But for all I know it's supposed to be fixed¹ in IE 8.
