mean that the following regularly happens?

1) The text box turns grey and I can’t type anything. Can’t even see the cursor on the screen. Just now I had to close and reopen Awimb in a new browser three times for this not to happen.
2) As I try to scroll down a page it shunts me back up to the top. Again, it sometimes takes three or four efforts for this not to happen

Any reason why this highly irritating sh*t keeps happening?
