Before filing a bug report please try the latest patched version and
if the bug is the the latest unpatched version.

Latest patched version is here (I am going to upload a new version today):

  http://ourcomments.org/Emacs/DL/EmacsW32/test/

The latest unpatched version is always on the download page (I do not
use or test that unless I am looking at a bug).
