Since build 6xxx i've had this problem with Gmail account. When i compose an email, the blank space seems to "extend out of my screen" and it does not have a scroll bar at the bottom. The only way to get it back to normal is by hitting "Enter". Also, typing emails from Gmail account seems rather slow in terms of responds. I don't get issues like that with hotmail or yahoo. i really can't think of a better way to explain this but i hope someone understands what i'm trying to say....or you can try it yourself if you have gmail. P/s: I've got "themes" turn on. Could be the problem but i'm not very sure yet.
