To make sure that there actually is a problem, let\'s eliminate all the other options first. In order to talk to an NPC or other character, you have to do one of the following:
* Right-click (is there a right button on Mac?) on the NPC and click on the
talk button (the button with a mouth on it);
* Or click on the NPC and press the ENTER key (I\'m not sure how it would be called on a Mac keyboard);
* Or click on the NPC and then click on the box where you type your message (clicking on the Chat window does not do the same).
If you didn\'t, then any keys you press are shortcuts to some commands, like T would start auto-walk and Q would exit the game. It happens to me more often than I like
