YES !!! 4.9.01 is working fine now, both GL and DX !!! My DLL in WinSys32 was only 68kb... so, I replaced it with the one you posted for me, which was 137kb !!! 3DCoat started right up...had to supply ser# and re~register too. I hope everything else on this old box still runs after a restart... LOL !!! Thank you for helping me Carlosan, and Andrew !!! You guys are the best !!! Mystery SOLVED !!!
Thanks to AbnRanger , and geoath for your suggestions too !!! Every possibility that's brought out leads to a resolve !!!
