Well, actually i have a similar problem : Fck editor (updated to the last version, which is 2.9.6), seems still not to be activated under mozilla (ver. 8.0.1) and chrome (ver. 15.0.

. Both makes fckeditor.html only downloadable. IE 8.0 seems the only one able to manage it. IE 9.0 opens it but several popup box are open empty (like "image property") could it be related to the php version on my server, or Chmods ?
