>>>You don't think so about which statement? I am positive the 4.00 refers to the Windows version. Further, I know that the DOS version in Windows 9x is *not* 4. Version 4.1 was, as Tom stated, the most unstable version of DOS released. Most people stayed with DOS 3.x (.2?) until DOS 5 came out. DOS 6.2 was the final MS-DOS release.
