Works like a treat, thanks, especially since discovering I'm actually
running Xfree 3.3.* rather than 4.* ....

Can't reproduce the problem at all - I've put message_ calls throughout the
code and they all work! Other than changing my XFree86 configuration back to
what it was, I can't think of anything else to try.

One request, Lars, could you move the error checking code which looks for
the Courier font in font_getfont_with_style into one of the initialise
functions so that if people have the same configuration problem as me that
they don't find out about it until they try and use text??

Thanks for your help!
