Can you try inverting the (now) two CreateWindowStation calls in
need_invisible so that the "CygwinInvisible" case is called first and
the NULL case is called second?

And, if that doesn't work, then try commenting out the
CloseWindowStation.

Also, what version of XP are you running?  Pro?  Is it up-to-date with
all service packs and updates?

(email debugging sure is fun)
