Well the running joke in our lab was everything on our GS Junior had been replaced except for the camera - when I pointed out that the computer was still original, too. Then of course, the next run, our Z400 computer crashed. We are now waiting for a replacement computer, that I'm assuming will have to have all the software reloaded and additional checks made by a FSR person. Has anyone else had issues with their desktop computer? Do people backup their data or store it for specified duration? Thanks.
