Robert,
Did you have to re-install Ezdok? Everythings works for me except for the middle mouse panning mode. I get the clicking sound, pointer goes away, but no movement.

I have the cheyenne v4 installed on my system with the same setup as you(win-7 64bit) with no problems at all. I would suggest asking the same question on their support forum at http://www.forum.aerosoft.com/index.php?showforum=106Hope it helps.Gabriel Silva
