Won't work. "start" launches XWin, then returns to the batch shell
immediately. So, the errorlevel is likely always 0 unless "start" can't
find XWin.exe. You wouldn't have a trivial way to check if XWin.exe
actually succeeded in initializing.
Of course, I didn't read the earlier part of this thread, so maybe the
idea is to determine only if "start" did not find XWin.exe, but I think
the user gets a pretty reliable error message if that happens.
