I can confirm that this does not happen in emacs -Q.

Thanks for the bug report, nurikabe.
I can't reproduce it with an Emacs built from trunk 2010-08-10 and the latest nXhtml beta. Can you please give me more details on how to reproduce it?
Seems to only happen if "Display Chunk Info in Margin" is active?
Thanks, I can see it now. I will look into it. (It is probably a problem with Emacs itself, but I am not sure yet.)
I have just filed an Emacs bug report for this and will decide how to fix it after some replies to it:
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=6915
This is fixed in my patched version of Emacs+EmacsW32, but the patch is not applied to Emacs yet. So this is not a bug in nXhtml. Closing.
Bug watches keep track of this bug in other bug trackers.
