Setting fonts in new frames

[Ewen Cartwright]

Hi all,

I set the font for my emacs sessions (ntemacs-22) in my .emacs file
thus:

(set-default-font "-*-Lucida Sans
Typewriter-normal-r-*-*-12-*-*-*-c-*-*-iso8859-1")

Which works fine. But every time I open a new frame I get plain old
Courier. I've looked for frame-opening hooks where I can run
set-default-font to get my own font choice in them but nothing I've
tried seems to work. Anyone know how I can achieve this?

TIA,
