Cygwin 1.7 beta XWin Crashs from Ubuntun 9.10 after Firefox sessions

Sun Nov 15 21:00:00 GMT 2009

Hi Jon, further testings show the issue is related to GNOME. XWin still crashed  after I started  GNOME-SESSION  and waited for some time without bringing up any apps. I',m able to ssh to the Ubuntu box and bring up xterm or firefox and do some work without any problems.  Since you can't even start up GNOME-SESSION, I am not going to pursue this issue anymore. Hopefully future upgrade will fix this problem. Thanks for your efforts.
