Font scaling does not alter the Family view frame/screen in the way that I would expect. Here is a family with the font set to 100%.
You can see that all the people names in the right-hand frame are all the same size, and all quite a bit larger than the fonts with the dates and places of birth.
Now I have set the font scaling to 85%. RM prompts me to close it down and re-start, so I have. Here is the same screen after doing so
Now you can see that the font with the name of the person at the top left of that pane (the ‘father’) John Watson of Clonbrogan is much smaller than the font for the other people in the same pane, and now about the same size as the font for the details of his birth, marriage and death.
Strangely, if I set the font scaling to 120%, then all the fonts seem to expand to the same extent, as you would expect
However, if I choose 60% (much too small for me in practice) then the fonts of both the mother and father’s name are shrunk too small.
I am not quite sure what is going on.
