Hello dear Lyxers,after upgrading LyX to version 2.2.3 opening and editing (linguistic) papers made with earlier versions of LyX does work. Conversion to PDF of each single child document works as well. But trying to generate a PDF from the master document results in an endless loop.
Any hint as to what could be the cause? The papers were made in Mageia 5, now using Mageia 6 Michael
