Yeah, check the Server-->Options screen. Set enter to the "Key broadcast" binding and uncheck the "State" box. Should work for ya. Note that if you get enter out of sync, it'll make things hard on you. I just set Pause to the key broadcast one and Scroll Lock to the Bypass one. Then when I need to confirm firewall prompts or lock the cursor on my screen for certain games, I just hit scroll lock. For pausing while chatting, I just hit pause before and after. Works well for me.
