I thought I had finally worked out how to use this workflow and entered six points to form an adequate set of seed tie points, but when I opened the table to review my work, all of the Image2x (x coordinate for image 2) were set to the value "1". Is this a known problem?

Are you using ENVI 5.1 or 5.0? I haven't heard of any behavior like you describe but there could be something going on. I used the tutorial data set to select 6 seed points, then stop editing and use the Show Table. The image coordinates were all unique and looked normal. Did you see the "1" value in your seed points or after generating tie points? Do you have the tutorial images to test this with? The tutorial data can be downloaded from our website if you are interested. You can find it under the Support menu.
