Thanks for all your kind pointers! Not!

Anyway I have dug around and found that it turned out to be a problem with
resources. In windows98/ME somehow resource IDs above 40000 (or perhaps
35656?) causes the .exe to become unrecognized.

Anyone is welcome to comment on this, but I am recording this so that
someone searching and finding my previous posts will have a clue as to what
*my* problem was.
