It appears that this is a fairly widespread error. Searching the Internet, I see many help pages out there (including the Oklahoma Bar Association, Longwood University, and the Cuyahoa Library) that mention the error. I can't find anything with more details or a solution, though.
Does anyone know which AOL browsers are affected? Is it just 9.0? I'm considering detecting the browser and recommending that affected AOL users switch to IE or Firefox.
