Thanks, I tried going backwards to 3.2 and something in all of those versions up until 3.4 plays havoc with my display graphics. Either with a card or onboard. Yes, I have Windows 10 modern upgraded, I perhaps could consider trying Windows 7. The effect is that the start menu flashes wildly when clicking on it plus mouse clicks anywhere on the screen are hesitant. 3.4 and above just don't work on Pro Tools 10 as you pointed out earlier. This is a secondary install of pro Tools in another room, for those occasions when I need 16 inputs hence using TDM, 96 interfaces and the HD2 cards I have. I am sometimes transferring 16 track tape to PT. My main workstation is Mac and 12.8 and is fine. EDIT: I just installed 3.3.2 on another Windows 10 (64) machine and the same graphic problem has manifest.
