It's always been some varieties of Arial, as I recall - this started months ago and there may have been others – so yesterday I dealt with duplicated file I didn't know I had, to the result that now I have single files of fonts I never use. And, again as I best recall, only and always in Pages. Huh?
Whatever, the "alarm" seems to be gone. If not, at least I have something I can do to hose it . . . maybe.
Paddy to the rescue.
Thank you, m'am.
