Hello. I need help installing GIMP and getting it to work. I have installed GIMP version 2.4.5 on my iMac G5 PowerPC running 10.4.11. I also have X11 version 2.0 installed on my computer (is this the right version?). When I double-click GIMP it attempts to open and shows up in the dock, but doesn't open anything. X11 does not open in the dock. When I double-click X11, nothing happens. No window opens. How do I get GIMP to start? Thank you. Any help is greatly appreciated.
