You know, for what it's worth, that's a sad loss for the sake of a font.
I can't really see the need to change fonts, other than size. I seem to remember in NATS there was some discussion about this for our in-house radar replay software - we decided on a sans-serifed font (Verdana, I believe).
Is it really necessary to change fonts? I would have thought the benefit of the arrows far outweighed a gimmicky font change.
Just my honest opinion.
