We're in the process of migrating from c3d 2009 to 2011 and I'm having trouble getting the buttons on my Calcomp DrawingBoard 3 16 button puck to work. I can use it as a pointing device, but I can't get the snaps to work. They seemed to work fine in 2009, but it's not translating to 2011. Anyone else experiencing the same or have a solution for me? Thanks in advance.
