I just upgraded the source code in svn to use the new final release of FCKeditor. Those of you using the mojoPortal source code from svn can get it now. After I've had a chance to do some more testing I'll make a new release. I've upgraded this site to use it as well so I can test. So far so good.
Update:
I'm having a few issues with the new FCKeditor and trying to work through them. Its not allowing me to browse the server or upload files on mono. It works in IIS, I think there is a case sensitivty issue somewhere but haven't found it yet.
Also the css for the editor is displaying funky but appears ok when it renders outside the editor.
