I believe all they are looking to do is create notes that can be attached to the image(s). IQ-View does that perfectly.
I am going though the manual now to learn how to edit or delete reports appended to the images. Intuitive would be right-click and delete, appears to be no option for that.
I am finding the manual to be quite helpful. Once purchased, I will print and bind it, deliver to the doctors. It is my experience some doctors are willing to learn on their own, and some want hand-holding. The manual should serve as a bridge between those two extremes.
