While there seems to be a break in the action I though that I would post this problem that I have once in a while. I am running a 15" powerbook 10.2.8 with 1 gig of ram. This seems to happen only when I am using Nikon software which I have to use because my nikon camera is tethered to the book. Here is what happens - The entire screen goes gray starting at the top and moving down to the bottom of the screen and there is a white box in the middle that says - You need to restart your computer. Hold down the power button for several seconds or press the restart button. I can not do anything until I do the restart. Nothing is lost unless an image was being downloaded at the time of the crash. This problem doesn't happen that often, it seems like only when a client is present. I do repair permissions once a week and I run mac janitor every so often. Thanks, Don www.distelphoto.com www.distelphoto.com
