Smartboard - very odd issue
I have a new smartboard, and it has been wonderful up to this point. All of a sudden, within the last week, I have this issue. You open notebook and start drawing, ( I teach physics and chemistry) and draw quite a bit on the board.
So I have a pen in hand, and while drawing it will suddenly switch to the pointer. If I do not notice this, then my drawing moves on the board. So I tap the pen button at the top again and start drawing again. Then it switches to the pointer again..and so on and so on.
I have triied recalibrating, and do not know what is going on. Any help would be greatly appreciated. Thank you
