Dear John -- Using the .bz2 you posted to this thread on Sept 7th
or so, I consistently get SIGSEGV on my Windows-7 box whenever
I Sleep or Hibernate the system. I include the .log file for your
Thanks for reporting this issue.
Does the crash also occur if you don't use -resize?
consideration, and the stderr output. Earlier versions seemed
to do ok. Is there a simple procedure for winding back?
If you've installed my snapshot as XWin.exe, the easiest way to get the
1.8.2-1 version back is to reinstall it using setup.

Unfortunately, I can't reproduce this on my Win7 system, although it is quite
possible that this is specific to the display driver or hardware.
If you can use gdb to generate a backtrace for this segfault, that would be
most helpful.
