I belong to a couple of message boards where I post and type messages - and I have had letters appear and disappear, I have also had a problem when I have gone in and tried to edit a message as the words just hang up there and will not allow an edit only a complete erase, and starting over.

ALSO I love the feature that spell check is already there but some times when the word is underlined as missspelled it does not work as it should giving you the correct spelling.
