Over the last week I have encountered an annoying problem.
I am drawing a large family tree and I am very careful saving it frequently. But the last two days, the file I have saved will not open and I get a message: “Can´t complete this command. Unknown type.” The file in question is much smaller than the working file, 6.2MB instead of 20.4MB.
Thank God for Time machine ! I can the go backwards through the copies there, until I find one that is ‘normal’. I usually work early in the day with this and retrieving a copy from the evening ensures that I do not loose anything.
I just do not understand why a copy from 09 PM will open, but not the original on my Mac the next day ! It may have been open in the background, but I have not done any changes to it.
Can anyone explain this.
I used v3.4.1 until today, when I upgraded to 3.4.2.
