font selection window

I just experienced an incident with Beta 16 where it would not show a fair number of the fonts I have installed (in any of the font selection dialogs). After restarting Scrivener, it showed all the fonts. But during the incident, it would only show a few. For example, any font beginning with the letter “D” wasn’t shown at all, and only a few others. I’m not sure what triggered this. Not only wouldn’t it show them in the font window, my normal text (“No Style”), normally set to DejaVu Serif, was being shown in Arial.

Has anyone else had this happen?
