Hi,
In various screens where there is a file list, there are either "Check-boxes" or "Highlights" or "Tick-marks". I believe there should be some uniformity. Personally, I prefer the "click and highlight".
When using "Star Alignment" for a mosaic, I need to select "Working mode" ---> "Register/Match Images" so I can add a list of "Target Images" and then select "Register/Union Separate" and now I can execute the process. To remove the "Target files" I have to select "Register/Match Images" because the file list is greyed-out.
Regards
John
