This may sound silly, but I've heard that SP2 is the best of all. In my last installation i had real prblems with 3D apps and games hanging, that was parently a very recongnised problem and there was a patch for it i installe dthe patch and did the reg modifications in case and I also installed SP4 (15Mb home version). Could this have been caused by My ATI radeon 8500 and VIA KT 4 mobo, aparently there are problems between using an Athlon XP processor (yep that's me) a VIA chipset (lucky me again) and Win 2k (what are the chances . So if anyone know much about this problem and can advise a good SP to download. Or would it just bea easier to install ME on another partition and use 2K for normal work? Thanks all
