I was working from the C code that Damon's Glade produces. He obviously
uses some unpublished calls. I will just output a warning if the gnome-libs
are too old and advise upgrading. I guess that I shouldn't be trying to
work-around bugs in old versions in any case.

You can see why XS confuses me. I used to call the set_build_insensitive() 
method via a Gtk::Pixmap without errors but I don't know that it actually 
did anything useful.

I will trust the documentation more and only expect what is documented in
future. I am still not used to having Perl/Gtk docs :-)

OK, I will not use set() for anything but bug-checking.

Thanks again, regards Dermot
