Not only that, but I note that my Mac does not have a visible disk-activity indicator; not surprising, really, as it seems to be thrashing like hell whenever I have the temerity to focus (i.e. click) upon another window. Now, my Mac's system disk is external (don't ask), and it has a barely visible blue LED, which is why I know when it thrashes sometimes. I intend to throw together a photo-transistor and a high-efficiency LED (plus a 9v battery) for a more visible "Danger! Will Robinson!" alert. -- Dave Horsfall DTM (VK2KFU) "Those who don't understand security will suffer."
