One of our smartboards has an odd problem which is whenever a teacher writes on the board it makes very jagged random vertical lines. I have tried orienting/calibrating/resetting the board with the notebook but that hasn't worked. Attached is what the lines look like. Has anybody else had this issue or know of a solution to it? Could there be something interfering with the pen to the board?
We're currently using the 600 series SMART Board Interactive whiteboards with a Macbook running OS X 10.5.7. Any help is greatly appreciated. Thanks.
