My young brother introduced me to GIMP last May. I bought the book with CD and set about installing. I thought I had followed all the instructions but ' Cashing fonts' was as far as I could get. At that time our Flat screen iMac (a retirement present to my wife) was running OSX 10.2. Since then we have installed OSX 10.4 from the Tiger disc and a newer GIMP downloaded from your site. We now get the message GIMP cannot open X11. Not much progress there then. It might help if I knew if I made a mess of installing OSX 10.4 and X11, or GIMP, but I don't know how to find out. I would still like to get started, could anyone point me in the right direction please?
