Thanks for the prompt reply. I will try your suggestion. I am on an early stages of a proof of concept project where we want to see how a trainee radiologist looks a xray image as against an expert radiologist. This is a non-profit/non-commercial research project.
However I have just encountered a major problem! My Tobii tracker stopped working after the latest Windows 10 update (build 16299.192)! Do you want me to create another discussion thread for this?
