Photobucket is no problem here either. Must have been a temporary thing.
Text entry issue is only on the mobile platform on my One X+. the old Desire is charging, will give that a go later to see if I can duplicate the problem. If I can, I'll try to videotape it and send you the vid.
Mind you, it doesn't happen all the time. I'd say once in every 10 or so attempts to edit. Just write 2 sentences, put the cursor in the middle and put a sentence in between. After some attempts, it'll go wrong. I've made 20 posts with my phone and had it happen 3 times.
