The hooks in the modified standard file dialog box routines have stricter
requirements for register saving under 5.03 than they did under 5.02.
I cannot remeber of hand, its been quite a while since I played with it,
but I think you must save restore basically everything (including the
direct page and data bank registers) for the hooks in 5.03 routines, while
this was not strictly necessary under 5.02, even though the docs said you
should. When I was first playing with it I found a few things that crashed
under 5.03.
