Weird problem...
 

I just got my new computer and when i played Jazz2 yesterday i was in a duel my chat didn't work! so i restarted Jazz2 and it worked again but after the duel when i was chatting it would only team chat and i couldn't talk to the person on the opposite team! :mad:

I hope someone knows the answer to this odd problem...

Try tapping the shift key when that happens.
