All NVidia drivers I've tried shut down properly.But 81.95, 81.98 + 82.69 do not allow to restart Windows [by running WIN.COM], after closing Windows to native DOS [C:\ prompt]. Actually all the drivers I tried for Windows ME shutdown properly....except these. Granted I only used official drivers from Nvidia with my GF5900. What i'm saying is I know it's not a problem with my Windows ME install. It never had a problem shutting down in the past until now, surprisingly.
