When saving my Archicad 22 file as a 21 file and open it all the windows disappear. It doesnt replace the standard archicad 22 windows with the windows in the 21 libary.
Ive used the 'Window 22' thinking it would replace with 'window 21' in the previous version.
Is backward migration possible with the new 22 libary? it has worked fine before (saving a 21 file as a 20 file..it replaces the windows automatically)
