Hi I am connecting and recieving messages just fine. My problem is when I try and reply in a chat window. I hit the enter key to send the reply and instead of sending the reply it does a carriage return. I dont see a send button to use and I also looked at the shortcuts menu and dont see a shortcut to send the return message. Can someone tell me what I am doing wrong or am overlooking here.

That's quite weird... Is that a problem just with facebook chat or with any other account?
Carriage return should be SHIFT+ENTER, while just ENTER should send the message. Are you sure that it's not the shift key of your keyboard stuck or similar?

You don't have to hit return on the numeric pad

Someone came to our IRC channel and discussed this same bug.

A bug was filed, and it was fixed. Fix will be in 0.5.2 (released soon)
