I've uploaded to the UK server the file titlesec3.zip.
Please, replace the content of
macros/latex/contrib/titlesec
by the new one.
It contains a new file titletoc.new which fixes a
major bug when partial tocs are used with include'd
files (a partial toc could appear in the wrong
context). Since it's a patch, the only change
required to fix the bug is to replace this patch
file.
i've installed the update as requested; thanks for the upload.
