Crap. The Mac Mini crashed again. It grey-screened. It wasn't doing anything. It wasn't being used as the media server, I wasn't copying data, it was just sitting there totally idle for several days, and I saw motion out of the corner of my eye, turned around and saw it had grey-screened. Most annoying. I rebooted it, and checked and fixed the disks. Once Anne is safely out of town, I will take it back to Apple for a fix. I checked and the warranty runs out at end of June.
