For people who've been using my TeX previewers, texx(X11) and texsun(SunView),
apply the following mods to file 'dvistuff.c'. The error manifests it self as
``jumbled'' letters, i.e. not aligned correctly. I'm suprised I didn't notice
it earlier & deduce the problem. You probably won't be able to 'patch' these
via 'patch' - you'll have to do them by hand.

I've also posted a new version of everything in pub/TeX/iptex.tar.Z on 
a.cs.uiuc.edu (anonymous FTP). I'll also post a complete update the previewers
in pub/TeX/previewers.tar.Z (it requires the other stuff). Recent features:
Complete tpic support, man pages, (thanks tim morgan), sliding while viewing
the exposed image, a cheesy ``restart where I left off'' attempt.
