Why is my Meaning Menu empty?
This question applies only to Lurch 0.75. In Lurch 0.76, some improvements were made to make this confusing situation far less likely, if not impossible.
This can happen if your current document does not have the correct dependency. Loading any topic from the File>Choose topic menu should fix that problem. (If you want to start your own topic from scratch with a blank document, choose the Meaningful Documents topic.) Lurch remembers the last topic you had open the next time you launch the program, so doing this once should fix the problem in the future. If you do not have any topics to choose from see this FAQ.
