Yes. That's not what my autodocs say.

Perhaps

That's more or less what I ended up with. My main problem was the use
of a font for menus/screen default. That did not work at all well unless
I did as you suggest first, then open the screen, not use the font, but
let the system find it in memory when it does screen bars/menus, close 
the screen when finished, and then close the font.
