Hello Brian,
I can reproduce this problem now.
The "Rigging Analysis" was a feature in older versions of COMPRESS. It displayed graphs of the distribution of shear force, bending moment, and bending stress along the length of the vessel as it was lifted in horizontal position at two points. This feature was removed at the time that lifting lugs were added. Due to customer requests, we plan to restore this feature in a more robust form.
Files made in the older versions and that had the Rigging Analysis option activated will show the "Rigging Analysis" in the Print List. However, there is no report for the Rigging Analysis and it is not listed in the Index. As you described, there is no way to delete this function (ie: the Delete dialog does not list the Rigging Analysis).
I've reported this to our programmers and asked them to suppress the Rigging Analysis from the Print List.
