Since a couple of days one of our boards doesn’t work well. It makes weird strikes when writing (see picture). Someone an idea of what could be wrong? I tested with different pens, problem stays the same.
We also recommend a direct connection between the computer and the board, bypassing any wall-boxes or face-plates and with USB cables no longer than three metres, or testing the connection with a different computer.
Should you need further help, please provide details on the model of the board and we will be happy to assist.
