Those jpg's aren't working By the way -- about the debugLevel 32 -- I was wrong, 31 was supposed to be showing everything but I commented out the lowest level debugging code to increase performance... Try doing this: after it hangs, go to the console and hit either Ctrl-Shift-Break or Ctrl-\ and see if it prints all the stack traces to the console. If you can, save those and send them to me.... It's frustrating because on my RedHat 7.2 everything is working fine (running over X11 since I don't have X installed on it).
