Large files from Graphics!!

We have a variety of Macs (Power and 68K) running Mathematica.  On some of
the PowerMacs (but not all) Mathematica creates very large notebook files.

Just a simple Plot stores as 100K, whereas on other systems it stores as
10K. Consequently 10 Plots create a file of over 1MB.  What appears to be
happening is that a large OMBD resource is being created with each
graphic.  The resource contains mostly FFFFs or 7FFFs data.

Now all settings/preferences have been checked and compared, and appear to
be in agreement between computers yet there must SOMEWHERE be a parameter
to tell Mathematica to save these internal versions of the graphics.  Can
anyone help here?

Going crazy...

Many thanks for any help you can offer.

John (with a disk full of enormous Mathematica files!)
