Windows 7 64 bit software or hardware update for Promethean whiteboards

[Roughley0]

We have recently replaced classroom computers with Windows 7 64 bit machines. Some of our whiteboards, different ages and models are experiencing jagged writing. The one I am trying to work on now is an Activeboard V3.75 build 1. Serial connection. Software Version 1.6.50464. Have uninstalled and reinstalled drivers and recallibrated. Have unplugged the board and left for a while just incase of static. Is there a firmware or software update needed ? Carol

I had some issues with 64 bit machines and Promethean. I spoke to support and they were really helpful - worth a call? Edited October 17, 2012 by witch
