I thought this editor looked familiar, my University (IU & IUPUI) has been using the same 'FCKEditor' for 5+ years now; nevertheless, it serves as our WYSIWYG editor for sending messages back and forth via our University's version of Sakai's (http://sakaiproject.org/portal) messaging system, I couldn't tell you how many times my session has timed out costing me a couple paragraphs of my time o_O
while I agree that F?CKedit is a lot of baggage and not very friendly to program against, the timing out sessions are a problem of the guys that implemented your messaging system and not a problem of CKedit.
