There is, however, a dummy root window when you run with -multiwindow.
Search the mailing list archives to my multiple responses on how easy/hard removing that dummy window may be.

I've been using Cygwin ever since the release of the multiwindow test server. It's been excellent! Thanks for all the hard work, especially Kensuke Matsuzaki for putting it all together in the beginning.
My question is this: Is it possible to run Cygwin Xfree -rootless without having to have the dummy root window? If not, why not?
