It was working fine for a while, but then something probably got corrupted, possibly related to running out of hard drive space. I moved my steam installation to another internal drive. Now Space Calibrator does not show up as an option in the Settings>Startup/Shutdown>Choose Startup Overlay Apps menu. I've tried uninstalling and reinstalling it, but no luck. I've installed other overlays, and they are still available.
