I agree that all the file conversion menu commands are broken.  (I am
using Mma 3.0 on a PPC 7100).  I have also experienced mysterious
horizontal lines running across plots which are otherwise OK, but have
managed to expunge them by increasing the memory allocated to psrender.
(Admittedly, I am generating some complicated plots.  But I had to allocate
more than 32M to psrender to get this to work!)

Incidentally, while using Display to save files as Mathematica Graphics
Format seems to generate a file that looks something like what you see
using "Display postscript" (or whatever it's now called), but I have
been unable to figure out how to get Mathematica to read this data and
show me the plot later.  Has anyone gotten this to work?

I managed to successfully write my entire PhD thesis in Mathematica 3.0
this spring.  I didn't have a problem with the lack of a spell-checker
that some others have mentioned - I've found that spell-checking
technical documents is usually more trouble than it's worth - but the
inability to put automatic numbering objects into tables makes creating
a decently formatted table of contents a real pain in the neck.
