I can navigate pretty good in all modes on my Droid 2, but can't post. In full site mode, I get all the buttons and boxes for the quick and advanced replies, but the actual text field is one line tall and will not allow me to enter data. In mobile mode, I can hit reply and type a message, but when I hit the posting button, the screen refreshes and does not actually post. Perfectly willing to accept that it is user error on my end.
