Thanks for the suggestions. I tried setting "Geometric" to "Custom Parameters" and then in the Optimizer tab selected x, y, z and barrel (in the lens settings). Then I clicked optimize and all of the images ended up on top of each other. So that didn't work so well. As far as control points, I have been working under the assumption that more is better. In this case all of my images are hand writing on sheets of paper, so I'm putting all of my control points on corners of characters. Any control points not on characters I've been removing. Using the 2020 version, the zoom with the mouse in the preview is working reasonably well. Although the preview still disappears on me regularly.
