# [texhax] bizarre tikz behavior with recent texlive 2010 updates

Sat Nov 6 23:10:29 CET 2010

OK, I admit I'm not 100% sure this is the optimal place to report
this, but here goes anyway.

I did
tlmgr update --all
the other day, and after that finished Bad Things started happening.

Boiling it down, here is a minimal non-working example (plain pdftex,
NOT pdflatex):

%------------------------------------
\input tikz

\hrule
\vfill
just a plain line of text in the middle of the page
\vfill
\eject

\end
%------------------------------------

The line claims it is in the middle of the page, but if I \input tikz
it is not.  If I don't \input tikz, the line is (more or less) in the
middle of the page, as expected.  Also, when I \input tikz, my page
number goes away.

I have a texlive 2010-beta lying around, and I get the expected
behaviour if I use that.

I suppose it is possible that a neutrino clobbered some bit on my
disk.  Before I reload all of tl2010 from scratch, could someone let
me know if they see the same behaviour?

Thanks.
Jim
