(I'm going through old bug reports that unfortunately weren't resolved at the time.) I'm unable to reproduce the issue in recent Emacs versions (like 28.1). Are you still seeing the problem? Skimming the rest of the thread, the discussion was about select-active-regions and whether to have it to `only' or t. It's still t (which, if I understand correctly, was the problematic value). -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
