[Message part 1 (text/plain, inline)]

When did you last pull?

The font panel isn't shown from Preferences for me.  Prefs should show  
the same as M-x customize RET.
(The prefs panel that we used to have is gone.)
Can you confirm so we can close this?

If it was there and showed the font panel, then I would absolutely  
agree with you...

Btw, even if it is shown (using M-x ns-popup-font-panel, which I  
blieve is the only way to bring it up now), it does not clearly show  
its association with a window.  This, however, is a Cocoa problem with  
the design of the panel.
