I'll have to look around for some. I doubt it was an UNIX path issue,
but rather 'current directory != app directory', which shows up pretty
often in the forums. Would you rather a note saying something like:
+             Note: This method is not recommended, since many Win32
applications
+             depend on the current directory being the application
directory, and may
+             crash or have other buggy behavior otherwise.
