sometimes when I'm typing a txt msg, email, google srearch, or anything involving a text box, text entry will just stop happening. this happens with the physical/virtual keyboard. i'll have a partial message typed out and even though it looks like the keyboard itself is responding to touch, letters & words stop showing up in the text box. switching back and forth from virtual/physical does nothing. i usually have to exit and close whatever app/text i'm in and start over. i did some searching, but haven't seen any other threads with this issue. anyone?
