After a while, somehow the browser looses focus, but you can't refocus the text pointer without switching tabs, opening tabs, or restarting the browser. I have also tested the beta on a Windows XP Machine, and it does the same thing, but not all the time... Reproducible: Sometimes Steps to Reproduce: 1.Signup for or Login to Facebook (If Necessary) 2.Open Facebook Chat, or Be sent an instant message (Whichever occurs first) 3.Start a normal conversation 4.Talk just like you would in any other browser, continue conversation until text input becomes 'unfocused' Actual Results: I have to open a new tab to allow me to begin typing again, usually stops midstream.
