I think that by using ex(run by windows in its own little dos
emulation memory section) windows lets the program believe
that it is accessing those memory address, but shunts it
though the windows system. When you use exw, Windows runs the
program normally, and hence doesn't try tricking it by
pretending it is a dos system.
