MS-DOS program starts only in full screen mode from command line
 

I noticed problems with window mode/full screen mode when running DOS
programs from the Vista command line "cmd.exe".
Let us take as example an MS-DOS program which you will find e.g. at INTEL.
It is the CPU command line identification tool CPUID.EXE. This program shows
up fine in window or full screen mode when started from the "cmd.exe"-window
until Windows 2000. When started under Windows XP in the "cmd"-window it is
not possible by any means to start this program in the original window mode.
It immediately shows up in full screen mode. Only after start in full screen
mode you can return to window mode by ALTRETURN. Under Windows VISTA BETA
2 the same effect. There is no start in window mode possible. Even VISTA
might hang (graphics driver?).

I suppose, that the full screen mode might be preferably enforced when a
C-programm compiled with MS-C 8.0/Link 5.60 (which I use) is too big and/or
has an overlaid structure as is the case with my DOS program! Many other
MS-DOS programs which I tested started in window mode and could easily be
switched between this mode and full screen mode.
Does anybody know possible reasons for this behaviour and why are there no
problems until Windows 2000? Might be, as Vista is still in Beta stadium
there could be a fix.
