Quick Reply Bug

I have been using the beta since it came out without much trouble. But I have noticed that when I receive a quick reply message while in an app and I click reply two things happen; 1. it takes 1.5 to 2 seconds for the message to come up 2. after I send the message and I go to exit the app by hitting the home button it will not exit. I have to hit the sleep/wake button then open the phone back up and then I am allowed to exit. Not a huge deal but a bit inconvenient. Is anyone else noticing this?
