Hi folks,

I've just recently experienced the joy of 64-bit Windoze, and its inability=
 to execute 16-bit DOS applications.

Interestingly, this problem also affects 32=3Dbit DOS applications, like th=
ose created with the WDOSX DOS extender. These are built initially as 32-bi=
t Windoze console applications, then stubbed with a bootstrap DOS extender =
which I guess starts as a 16-bit application.

So,  does anybody know if there's a way to stub 16-bit or 32-bit DOS applic=
ations so that they'll run on 64-bit Windoze, sort of like a reverse DOS ex=
tender (well, in the 32-bit case)?

Joe.
