Mine, too.  That's why I stopped running compress - I just get
everything batched but uncompressed.  It's slower, but fast enough, and
works well.

It might be, but I upgraded my system from 1 meg to 3, and it really
didn't help much.  The 16-bit compress is right near the limit for
process size on V/AT, and it seems to swap a lot regardless of how much
memory you have.  You might want to look at the 13-bit compress, I
understand it is much faster, especially on brain-dead architectures
like the '286.
