FM 7.1

I've recently installed Framemaker 7.1 and finding it an excellent ddp program.

Using the table custom ruling and shading is giving me issues. When I apply a custom ruling to a cell, row or column, then apply, save close the file then open the change are unsaved, any ideas what I am doing wrong, I've been reading everything available on custom ruling and shading and cant seem to find an answer.

Any help would be gratefully received.
