I saw much more dramatic phenomena than that, as described above.  Or
are you saying that PMODE couldn't jmp to the program's entry point
and only *after* that crashed?

Any idea why cannot it pass the execution thread?  Perhaps you could
elaborate a bit about what exactly happens that prevents it to jmp to
the entry point.  To me, it looked as some memory managing problem
(when it didn't hang immediately ;-) because CWSDPMI said something
about page tables.
