When I was trying to change the font in my xcode, I accidentally dragged a typeface out of the dialog with the mouse, causing the typeface to disappear from the fonts dialog forever.
As you can see, Menlo Regular is gone, (Italic too, because I couldn't help myself, damn me) I can't select it anymore. Funnily enough, you can't drag the typeface out of the window on another machine here. How would I get it back?
For clarification, the typeface is still available on the system, just not in that dialog.
