Thanks! - That's cleaner than the hack I finally ended up using.

Ah, so I've discovered (the version of YesNoDialog.icn in the unilib
cvs respository attempts to allow you to change the font size of the
message area)... The code there 'sorta' works - you can change the
font with a (new) setFont(font) method call, but the size calculation
doesn't use that new font yet, but rather the 'default' font for
the Dialog.
Part of the problem is that knowing the font doesn't seem to be enough,
as TextWidth() requires a window. [It would be nice if TextWidth()
would also accept a font (as in, say:
width := TextWidth("sans,24",mesg)
then all my troubles (ok, a few of them, anyway) would go away!]
Thanks, Clint - you've given me helpful information!
