Since Frontpage Slideshow uses a lot of AJAX functionality, all third-party editors caused issues, because they are "invoked" differently from each other.

So we took a convention: we would only support the default editor, which is TinyMCE. Either way, if you link to existing content you won't use the editor or if you add custom content, it's so little you don't really need the benefits of a better editor. So we load TinyMCE by default.

Now, since JCE is basically an improved version of TinyMCE, we will try to add support for JCE only in the upcoming release we plan the next few days. If for some reason this causes issues, we will document that specifically in the release announcement.
