startx hangs on WinXP

I've installed the latest version of cygwin and cygwin/X.  When I attempt to
use startx in multiwindow mode,
the X server hangs.  

If I use either of the following, I get the X server started, but I don't
have a useful window manager.

startx -- :0
XWin -clipboard

I tried the identical installation steps on another XP machine, and all
works fine.  
So, there is something strange about -multiwindow which is stopping me,
And it appears specific to a particular XP machine.

Any ideas on how to debug or isolate the problem?
