Hello. Please help me solve the problem with the interactive whiteboard ActivBoard 78 Touch. When connecting the board to a PC with Windows 10 OS, the mouse cursor does arbitrarily press the left mouse button, intercepting user control. Disconnecting the USB cable from the PC helps. I tried to solve this problem by myself updating ActivDriver to version 5_18_19_x64, as well as removing all Promethean software, it did not help. I suspect a driver conflict with Windows 10 updates, but I do not know which of the updates is causing the conflict. There are 42 sets of ActivBoard 78 Touch equipment in our school, almost most of them have this problem. Please help.
