I got this strange problem, currently it seems to only be a problem with replies to whispers(as far as I can remember). I get a whisper then I reply a few times, and suddenly everything I type is in caps. Clicking a textbox control in another non-wow window solves it. Nope, caps lock does not come on, I've already checked that.

Anyone else got this problem? Not a huge deal, but just wondered if someone has the same, and have found a permanent fix for it. Using Win 7 64 bit.
