Been having this problem since last night. The Twitter application seems to be frozen on my BB. When I move the keypad over to Twitter and press to open, nothing moves or seems to. Twitter application does not open, nor does the keypad move. I have to press the close call button to get the keypad moving again. I do get updates and notifications of new Twitter messages but like I said, cannot open to read. All other functions or applications seem to be working well.
