Windows NT4 supports flash player 7.0.73.0 when using IE6. If you use Firefox 2.0.0.20, Seamonkey 1.1.18 or K-meleon 1.5.3, NT4 supports flash player 9.0.47.0 as the latest version. I agree that NT4 is fast and stable I run it on an IBM netvista 8311 with a P4 2.53GHZ, 1GB ram and onboard ethernet and video. It dual boots with 98SE (RP9, KernelEX)
