I get the following error when I run startxwin from a cygwin (1.7.20) 
prompt on my windows 8 surface tablet

"A fatal error has occurred and Cygwin/X will now exit

Caught signal 11 (Segmentation fault). Server aborting

Please open /var/log/xwin/XWin.0.log for more information

Vendor: The Cygwin/X Project
Release: 1.14.1.0

Package: version 1.14.1-1 built 2013-05-07

XWin was started with the following command-line:

X :0 -multiwindow"

I have also attached the /var/log file indicated...

Any help would be appreciated.
