I recently upgraded to Snow Leopard after the latest update to X11 required it. Now whenever I launch gimp, I can't do any work. Why? All the text/letters are replaced with boxes or squares. I've restarted my computer, uninstalled and reinstalled (both gimp and X11), but I still haven't been able to solve my problem. I've provided images below to help describe my problem. Does anyone know how to solve this problem?
