Hi,
From my research on the description box, it uses the fckeditor as an IFRAME.
http://www.fckeditor.net/
They have suggested they may be considering a switch to a different editor. Maybe that means an update to a newer release of the fckeditor.
I haven't seen the "ghosting" occur recently, i.e. where the frame would load and fade-out. I have seen the frame simply fail to load, often with a site problem

Edit: Hmmmm... I just looked at the page code and see the query string for the frame call. Since it's somehow having issues with a caching problem or maybe a proxy server in path (not pervasive), I wonder if adding a unique string to the query for each call (like date-time) would clear the load problem by forcing the cache to refresh.
Edit2: Ooops....I apologize to the Auctiva folks if that's back-seat coding. I'm just taking the broader network-engineering view of why some seem to have the problem more consistently than others and clearing cache isn't always working (but seems connected to the problem).
