I may be wrong, but I think MS Flight Simulator does not run under
MS-DOS.  Yes, you can execute it from MS-DOS, and you can also boot
it directly from its distribution diskette, but I think that once it
gets control, it takes over.  You can't exit from it and return to
MS-DOS, can you?

When it is booted, it assumes the machine is reset.  If you execute
it from command.com, it probably assumes things are in a relatively
quiescent state.  If you've got TSR's floating around hooking
interrupts and such, you've probably perturbed the environment
enough that a standalone program like that one can't figure out
what kind of a machine it's in.
