Minor Chat Bar Troubles

[sankto]

Am I missing something or is there a reason you can't just...toggle the button off?

When i have it off, there is nothing in the input bar. I have to type "say" everytime i want to say something.
When it is on, i cannot clear "say", to input a command, without having to select it with the mouse + backspace.
It might be the "working as intended" situation, but i clearly remember it not being the case when it was on.

To add to problem #2, when numlock is off, i can move with the number pad (but i never use that anyway), but still not press / * - + in-chat. When it's on, neither work.
