My emacs (x) is still not running at all on my windows XP virtual machine. cygcheck output from both machines attached. Recap: I have a Windows 7 64 bit computer running a cygwin x server, completely up-to-date. On this server I have a Vritual Box Virtual machine running 32 bit windows XP with cygwin completely up-to-date. The DISPLAY variable is set to the X server on the windows 7 box. The problem is that running emacs (typing "emacs" to a bash prompt in an xterm or in a bash window on the XP VM) on the XP VM fails silently - no core dumps, no messages, nothing to be found in /var/log. "emacs-nox" works fine.. This setup was working fine until some time after the end of August (I update cygwin on each computer weekly). I installed emacs from cygwin on the Windows 7 computer (after creating the cygcheck.out) and it runs fine. Linux emacs in Fedora VM also works fine on the x-server. I created a second fresh 32-bit virtual machine with windows XP and installed a fresh cygwin. emacs crashes in the same way there. Any help would be greatly appreciated. Thanks Gulliver
