Our developer will be working on RCF over the next few weeks. Things may look wonky at times, normal functions may not work or dissappear completely. It's the nature of the beast but we'll try to make sure this is painless as possible.
I'm having the same problem with images. Strangely, sometimes it works perfectly fine. Other times my image gets inserted into my post but then immediately disappears. I've had the same issue with emoticons a couple of times where they would appear and then quickly disappear.
