This font menu problem is something I noticed myself even with normal
applications like Ink. What happens is that the font menu takes focus
and then the changeFont: action is send down the first responder chain
to the font menu itself. No idea why this happens. It also depends on
the window manager in use. It did not happen to me on KDE until early
this year, when it change for unclear reasons.
I will need to investigate this in detail at some time.
Cheers
