Actually, very concerned indeed about this now. Until this is fixed, unless I'm mistaken, the control cannot generate semantically correct XHTML markup in the second most popular browser on the market - surely that goes against all of your marketing claims?
I totally understand small bugs will crop up here and there, but this one is fundamental to the correct operation of even the most basic functions of the editor, namely being able to add add heading tags etc to body copy.
This I would hope is absolutely top of the queue to get fixed, as until it does, I don't see how it can be used to any great effect on up to 20% of the browser share.
Correct me if I'm wrong?
cheers
