Contrail One, unarguably the best font on offer, has the annoying problem of tripping up the system and defaulting to Arial on occasion when you click on the text box. Looking at the properties of the text box, it seems the font is sometimes being recorded as "Contrail" and other times as "Contrail One" --- I suspect the space is causing problems. (Maybe this is more of a bug report? I dunno. But either way I'm suggesting it! :) )
