Cygwin X and XInputExtension errors

[Matthew Carpenter]

I have been having a devil of a time getting X to work properly between a
Cygwin X server and a SuSE 8.2pro box set up as a X-Terminal Server.  Here
is the message I most recently got (this is using SSH with XForwarding).
When attempting "X -ac -query myserver" I get the same message with
different display info, and xdm never shows up...
Does anyone know what causes this?  XInputExtension suggests that perhaps
there is some library extension in X4.2.x which the Cygwin X-server doesn't
support, and is heavily required throughout KDE and Yast2, but not in xeyes
(my favorite X tester).  TIA

Xlib:  extension "XInputExtension" missing on display "localhost:11.0".
