Understood guys, but I have a rather large video with large tracking area that takes maybe 7 hours to track. I needed to be able to use the PC for other tasks as well besides tracking, so I decided to try something. I set up AE on another unused PC here and I do have a KVM switch here so I can switch between PC’s. I thought using the normally unused PC for tracking would solve the problem, but when I switch screens, the tracking stops. So essentially I can’t even KVM switch PC screens without the tracking stopping. Any thoughts? I really need to have my main PC free while the other tracks and be able to switch screens without a tracking stop. thanks, Jon
