First off, petulka77, you registered and posted 1 time to tell him to get a better browser? What a waste of your time.
This can occur on some sites that use old coding that isn't compatible with IE9.
On the sites this is occuring on, click the little icon in the address bar that looks like a torn sheet of paper - when you hover over it, it should say "Compatibility mode". It should reload, and the error may stop.
Let me know.
