Warning about Adobe 8

[Michael Barr <barr@math.mcgill.ca>]

Whatever you do, do not upgrade to Adobe reader 8.  I found this on the
texhax list.

It turns out that files converted (from the ps file) by the distiller
(which costs something like $500) do not have this problem.  I guess Adobe
is tired of free use of their format.  At TAC, we still consider the dvi
to be the official format.
