Thanks Joris. Bugzilla has been raised. I was wondering, though, if you have a copy of that older "stable" version of libtiff hanging around anywhere? My problem is that we have 2 clients here with TIFFS (numbering in the hunderds of) like the sample I have provided, and they need them rendered into PDF format. My alternative is to go back to the old ojpeg, and hook my old patch back into libtiff 3.7.4 - which in my books is a bit dodgy. Thanks again mate.
