[EpiData-list] Dialogue Window "Define Entry Rights" does not appear

Hello List, hello Mr. Lauritzen, in a subproject a local Admin is defining Groups and Users. After that she wants to define the Entry Rights, but the window doesn't appear. She tested it on 4 different PC (WIN 10/newest EpiData Version) with no success. With me on my Installation it works (Win 10 and newest ED too). I wonder how I could help her. Are there some tipps how to find out what kind of problem exists? Perhaps a workaround? Kind regards Michael
