So, no suggestions :-(
I'm looking for anything at all that I could put into my .XWinrc that
might produce some diagnostic output short of running XWin under a
debugger. I'm completely guessing that it's a permission thing.
As I mentioned, I *can* launch X applications from a Cygwin mintty shell
console after setting DISPLAY, including being able to launch things
like Emacs, so whatever is stopping these from displaying, it's only
affecting things launched from my .XWinrc.
