Hi Kai,

It's expected that the .exe won't work when separated from its DLLs.  It's
interesting that it works at all, though: there's a missing symbol somewhere
in the dependency chain, but evidently one that's only accessed when
OpenSlide is loaded into Python?  I can't track this down right now, but
I'll try to take a look when I get a chance.  Meanwhile, if you get anywhere
with it, let us know.  Checking for Dependency Walker errors on
libopenslide-0.dll might be a good place to start.
