Javascript-Errors with IE?

Is it just me: I have activated to show javascript errors in IE. On the forum and on the demo gallery I get many javascript errors. The error-window popups 15 times when I enter a thread on the forum. After every letter I write in subject form field under "submit forum topic". Also on the gallery itself. On the submit comment page the warning window popups all the time.

When I visited your page some weeks ago I did not notice any error although I have activeted the javascript error popup all the time to see javascript errors on own pages immediately.

The firefox javascript console only lists some css errors.

Anybody else?
