We just upgraded to the new version of ARIS Designer (7.1) and the Fragments pane was working initially, but after some editing it completely crashed for me and will not display anything.
I had highlighted some items and right-clicked and chose "Create Fragment", now nothing appears at all in the pane not even the default one, and even when I try to create a new fragment nothing is displayed in the pane.
Any help with this issue would be much appreciated.
