Private Message Reply Box Blanking

Okay, this is starting to annoy me, to be honest. >_>

Over the past little while, my messages kept having letters disappear from some messages, like the = sign disappearing from my emotes.

Now; I can't even send a PM in one of my conversations, simply because every time I try to do that, it blanks the box, and gives a 'not enough characters' error! Obviously the error isn't the problem, but rather the fact that it blanks the text box, as the error wouldn't appear otherwise.

I keep trying, but it just doesn't work... I have a funny feeling this is because of that upgrade as well. =/

/EDIT: Alright, I got to send the message, however, it might be because I have to separate things a lot, and use different brackets and the curly braces to separate some of the discussion points. =/ It probably just finally didn't like that anymore. =P
