 Speaking about GNU, I wholeheartedly recommend SumatraPDF which is a
GPL PDF (and not only) viewer for Windows, see

http://blog.kowalczyk.info/software/sumatrapdf/free-pdf-reader.html

for more details. It is very simple to install (you can even about
installing it entirely), very fast to open (without using tricks such as
"preloading") and just generally very streamlined and convenient to use.

 Actually this is not so very mysterious, just a (harmless) bug in
wxWidgets which gave this spurious debug error under Windows XP only (which
is why I hadn't noticed it). I've just fixed it here:

        http://trac.wxwidgets.org/changeset/78048

so if you use an updated wx version, you shouldn't see it any more but,
again, the error is harmless and is just due to an unexpected error code
being returned under XP.

 Sorry for failing to realize the real reason for this message sooner,
