XWin crashes with "Fatal server error" when starting SYBYL 8.1 over SSH

[Patrice Peterson <runiq at archlinux dot us>]

Hello,

In our lab, we use Cygwin to run SYBYL 8.1. SYBYL does not run locally,
we instead forward the X server of the remote machine where it is
installed over SSH. This used to work fine until a few weeks ago, though
I am embarassed to say I can't pinpoint the exact time when it stopped
working.

SYBYL usually opens two windows, a main window and a (graphical)
terminal. When the first (main) window pops up, XWin crashes with the
following error:

    Fatal server error
    ...
    Package version: 1.12.1-1 built 2012-05-02
    ...
    X was called with: X :0 -multiwindow

An full Cygwin update didn't rectify the problem, and IIRC it's not
possible to downgrade packages in Cygwin.

The corresponding /var/log/xwin/XWin.0.log is found on my
dropbox [1], as the list's spam filter won't let me post this mail
otherwise. The output of cygcheck -s -v -r is there, too [2]. If I
should post those files elsewhere for persistence, just let me know. I
tried following the advice on [3], to no avail.

Regards,
Patrice
