Umm, all i can suggest is are you using DOSBOX ??? I know you think its not a software issue, but sometime it can be, Some newer cpu’s, i have noticed, sometimes are not compatible with older software, which confuses me a bit, but its gotta do with them not adding the support for newer hardware… I know Vdms had these issues, but so far DOSBOX has worked like a dream for me and my buddies, and we all upgrade our hardware quite a bit. SO i cant see Dosbox not working for you… The best you can do is try… But thats quite a strange problem you have. I hope i have helped in some way… Please let me know if dosbox worked for you, or just give us an update on your progress… the more info i get, the more i can try and help. Best of luck.
