Interactive WhiteboardsDisable touch on activtouch?

Yes, this would be on using the board as a whiteboard or inadvertant touches when the projector is not being used. Examples projector is off, teacher is conferencing with students at her desk so computer is open, students walk by and graze the whiteboard moving the mouse and sometimes clicking on icons on the computer. We have investigated exiting ActivManager, but haven’t found an easy way for teachers to restart short of “restarting the computer.”
