I have this problem.
I can't use the "Style" or "Format" menu.
If i select some text and apply (i.e.) Heading 1 Format, nothing happens. The same with the "Style" dropdown menu.
The only thing that "Style" works with is the table. I waas able to make an entire table looks like the selected "Style" (i.e. "Blue Title"), but not the single cell.
It seems that other people have this same problems.
Do you know why?
P.S. the same problem happens on the http://www.fredck.com/fckeditor/demo/ editor
If i add manually the "class" tag i can see the result on screen.
