Dear all. When the GUI freezes on me its a complete freeze with no pop up dialog boxes. This means the job history is not recorded and no results are recorded in the GUI. I'm not sure if this is screensaver or desktop switching related - it only seems to happen randomly - mostly when running long jobs where nothing much happens on the screen, in my experience. I'm also using an nVidia card and an upto date version of the X-server (on my ubuntu 9.10 box). I agree this is a minor issue compared to having a great program which works well. But it does mean that if its easier to use a command line all your hard work with the GUI (and its enhancements) will go to waste...
