In FMPA 13 help
To configure the Font menu in Windows:
If you are in Browse mode, click in any field that displays text (any field except a container field).
Choose Format menu > Font > Configure/More Fonts.
Sorry I don't have answer.
Some programs containing Word 2013 (not only third party!) don't respect hiding setting in font control panel.
"configure/more fonts" option was in old version of FM. At the time FM had its own font list.
