Ok, I just checked this out using an Ipad running iOS 5.0.1 and the chat bar stayed at the bottom of the screen like it should. I also checked it on an Iphone running iOS 5.0.1 and again, the chat bar stayed at the bottom. I also check ed on my Ipod running iOS 5.0.1 and again, same result, the chat bar stayed at the bottom of the screen where it is supposed to be and did not hang in the middle of the screen. What iOS are you running?
89Flyboy... What phone do you have?
