Promethean + extra mouse weirdness.

(Not sure if right subcategory, but hey..)

 

Hi guys.

 

Promethean board (AcitvBoard to be precise) connected to a PC via COM - this works perfect with the pen.

 

However the attached USB mouse does not, when moved it will always jump back to the spot where the pen last touched the activboard (and equally if the pen has not touched the board since powering the PC on then it will not do this weirdness).

 

I have tried completely removing the drivers for the activboard and reinstalling, on a side note this began happening about a month after putting in a few promethean power supply.

 

If I pull the power out of the promethean while it is doing this then it will work correctly until I plug it back in and touch the pen to the board.

 

tl;dr - Mouse cursor always flys back to last point the pen touched.

 

Any suggestions? thanks.

Nevermind - fixed it.

 

Plugged it in via the Promethan Board's secondary input (box on the wall) and that does not have the same issue - did not try this earlier as did not have access to it when class was full of kids.
