Thanks, Paul. No spyware, viruses, or anything nasty, and it's completely free (there's an invitation to make a donation, totally voluntary, and no nagging). It's called Cumulus, works with the Davis Vantage Pro and Pro2, and Oregon Scientific WM-918 and WMR-928 (and similar stations with slightly different numbers). It doesn't work with the WMR-100 (yet). It's for Windows, tested on XP and Vista. Should also work on Windows 98 and 2000.
