This is how a text looks when it gets typed in (while being alt+tabbed to windows) during the time that a char is loading.
Also after chars finish loading the key remains pressed and the first emote - without correction looks like "´/hail".
This bug is in the game for years now, but it has become worse with Windows7/8.
I don't know how it is on a english keyboard, but the char is the symbol on the key for quickslot 12 (I think, once I thought it was the key for auto attack, but I think I was wrong then).
It's VERY annoying to see half of the emotes being written to chats.
Edit: Of course people bugged this over and over. And I also just realised that the post didn't contain a suggestion, so the suggestion forum is the wrong one.
