Linux file system is very different from Windows. So different, that Windows
cannot even see Linux files in the same computer.

With Mystic, this causes a lot of little problems, and a few big problems.
You just found one of these problems.

Again, Windows and *nix are very different in how they use files. There is no
easy solution to that.
