Slow rich text editing on web

Hi everyone,

I’m having some trouble with an editable rich text on a web form. Users complain than changing the font size or font face takes a couple of seconds to perform. And it gets worse with the length of the text.

The field is a regular rich text field which is displayed using the “Best fit for OS” option. Since we only use IE7 (windows vista), it uses the Dojo editor.

Does anyone have any clue?

Thanks.
