Re: GtkExtra under windows 98!!

Hi Adrian,
             I would be more than happy to write an FAQ on using MinGW and 
gtkextra. It may take a few weeks though as I am busy trying to finish off 
a presentation for my software application (P-Syn) which uses gtkplot!

I will let you know when I have something to review - hang in there!

Regards,
Richard.
