After I upgraded to WP 2.1 the rich text editor is not working properly. The problem was not resolved when upgrading to WP 2.1.1 either. The problem is that the formatting-buttons for bold and italic text doesn't work properly. When using Firefox absolutely nothing happens when trying to format the text. When I try with IE this message pops up when pushing the "bold"-button:
"Are you sure you want to navigate away from this page?"
If I click "OK" nothing happens with the text. If I click "Cancel" the formatting applied. IE reports also another error message on the "Write" page in WordPress:
"Error on page"
Error: Object doesn't support this property or method
Any clue what's wrong?
