It seems that the Denemo Upgrade procedure which is supposed to copy over your personal shortcuts menu commands palettes etc has not been working for some time; in fact I notice that the upgrade dialog does not mention copying over your custom-built menu commands and I can't see any code that would have done that. I have now fixed this, so that every time the Denemo version is bumped you can just take the Upgrade option with confidence that everything will be copied over to the new version. Should you find this confidence misplaced *please* let me know...
