Thanks for the suggestion. I ungrouped one of the graphics, then
selected each object individually one at a time and deleted it. I know
what you mean about extra artifacts - I've seen that many times with
imported PS files. But this time there were none at all that were not
necessary.

I also discovered something else. Before adding the 12 pages and 36
groups of graphics the file size was 37 MB and now it is 97 MB. More
importantly, Scribus used to take a mere 700 MB of RAM while working on
the document, and now it is sucking down 2 GB. The computer has 4 GB of
RAM, so it is not using the swap, but that is still a lot of RAM. I am
guessing that when I load the file Scribus is imaging into RAM every
object in the entire document, not just the objects it needs in order
to display the pages that I ask it to display.

I went into Preferences and set it to use only two undo levels, but
that didn't seem to help much.

I can work in the document, it's just taking a very long time.
