Since the beginnings of FM the list of Graphic Frames in the Paragraph Designer is ordered in the sequence of appearance (or the creation?) on the reference pages. IMHO this is a bug and I filed it therefore.
If the list becomes longer than just 5 items it becomes difficult to spot the right thing.
IMHO this list should be orders the in the same manner as the lists in catalogues. Hence it also must observe the ini setting for SymbolSortingBeforeAlphaNumeric.
