startx crashes, xinit works

[luke.kendall@cisra.canon.com.au]

I find that after installing the latest version of Cygwin just now, X
crashes if I try to start it via startx (not starting with -rootless or
-multiwindow), with the error 

wmaker fatal error: it seems that there is already a window manager running
waiting for X server to shut down xterm:  fatal IO error 104 (Connection reset
by peer) or KillClient on X server ":0.0"

The Xwin.log ends with:

winMultiWindowXMsgProc - XOpenDisplay () returned and successfully opened the display.
winClipboardProc - XOpenDisplay () returned and successfully opened the display.
winClipboardWindowProc - WM_DRAWCLIPBOARD - Initializing - Returning.
winClipboardProc - Call to select () failed: -1.  Bailing.
winClipboardProc - XDestroyWindow succeeded.
ddxBeforeReset - Hello

winClipboardIOErrorHandler!


Yet I can start it up if I run xinit.

Any suggestions?
