[Fixed] Windows 10, wont save/load from some drive roots

[dgud]

The old wings is (or rather erlang is) compiled with an old compiler, so windows might do some trickery there for old programs should still work or something.

With 2.1
I can save (and load) to D:\ and I get a proper error message when trying to save to C:\ as it should.
I have an old (upgraded) machine where D:\ existed before upgrade to windows 10 though.

I wouldn't classify this as a bug though, if windows don't want you to save files under root don't or you will get into trouble. :-)
