Cygwin/X error

[Yoko Ookita]

Hi,

I have a trouble with the following situation.

When I run startxwin.bat on Cygwin, 
Cygwin/X output the following message, and exited.
--
XWin was started with the following command-line:
/usr/X11R6/bin/XWin -multiwindow -clipborad -silent-dup-error
--

But I can't find XWin process by 'ps -ef'.
I can't find by Task Manager of Windows, neither.

If you know what I should do to start XWin normally,
please let me know
