SMARTboards and OneNote freezing

[telspar]

We are running Lenovo L13 laptops with various SMARTboards, mostly 6000 and 6000S series. When users connect to these and use Microsoft OneNote for drawing on the board, we are seeing frequent laptop freezes and crashes. So far we have tried updating video drivers, removing SMART Product driver, and using both versions of OneNote. So far nothing has worked. Anyone else seeing this issue or have any suggestions?
