Hi, I developed an extensive commercial dos program back in about 1990 and am still selling it today. It is a Microsoft Dos program compiled using Borland Pascal and it uses VGA graphics and I have had no problems running in all versions of Windows since. However the Beta 2 version will not run the program. It comes up with a fatal error in NTVDM.EXE when trying to run the program. Apparently, the Vista Beta II release will not run any full-screen graphics Dos VGA programs. My question is, does anyone know if Microsoft are attempting to fix this problem for the full release, or is my program history ? It is something I need to know as my livelihood depends on it and I need to start thinking about alternatives now if Vista will not support VGA Dos programs. Regards, Peter in New Zealand.
