Started happening in RC1, and happens only randomly, but often. When we edit a post, html tags i.e. <p> and </p> appear in the editor box, and remain in the post after saving. I asked Mike about this, and he said it could be the RTE failing to load when editing. EDIT: This is happening in both FireFox (for me, steven s and several others) and Safari (for Dragonfly). In IE, it is just fine.
