I probably use the Talk app more than any other. Often I use the portrait view of the virtual keyboard for typing messages. On a few occasions now I've gotten the Force Quit dialog because the keyboard has apparently locked up. (Symptoms are the cursor not blinking and the inability to type.) I hit "Wait" and it comes back on its own within a minute or so.
Just wondering if anyone else is having virtual KB issues (in the Talk app or otherwise), and if this is one of the "known issues" to be addressed in the rumored upcoming patch.
