when req-force = 1 a detach_window_thread( top_window ) is called.
If I start the same or two different 16 bit programs the second one is started
with force =0 and has the same thread as the first. This causes a crash.

I have not been able to determine what make the force=1 vs force=0 between the
first program and second program.
