Enter Button Crash

Sometimes when I press "Enter" button to type in chat or to see chat, the game crashes. It usually happens after I have some other business on windows. I use alt+tab do other stuff then back to game play a little more someone sends a trade whisper so I press "Enter" to whşsper back *bam* the game crashes.
