on my curve. everytime i try to post a message in my bbm group, after about 7 or 8 words my cursor disappears and i can no longer type in the send box. if i scroll up my cursor appears in other previous messages but when i scroll down i cant put it back into the typing box. i can scroll to the right to the send icon but not back to the message box. i have to reboot to get it back and it does it over and over. in my reg bbm. i can type an entire story with out any problems. its driving me crazy
