You just dredged up memories of trying to run Thief: The Dark Project on Win2k and the installer failing, until I found an obscure forum post saying I should just run the installer with the "-lgntforce" flag. Dear god, the stability gained from running on a sane OS! On Win98 on the same hardware I was forced to save early and often or risk losing hours of patient sneaking and hiding when the OS inevitably borked out.
