  I've experienced similar things.  I'm assuming it has something to do
with how the program you're trying to crunch is written.  I wouldn't
recommend crunching stuff in the C: directory.  Most of the commands
are small anyway, and crunching command files will make them unpure.
(i.e. you can't make them Resident)

 I have in the past tried using Powerpacker on utilities that I only
used occasionally.  It worked fine on Handshake, and such.

 I gave up trying to use Powerpacker when I got my harddrive.  The space
savings wasn't a big deal, and it wasn't making it slower to load programs.
In certain cases, when using a floppy it seemed to be actually faster
to load a crunched program, than to load the original program.

 Doubtful.  The program you are loading the data file into will need to
know how to decrunch the file.  Some programs like PPMore do this.
Depending on what you're doing, anther option might be to use Pipes.
I've never done this with AmigaDOS, but you would be taking the output
from the Decrunch program, and using it as input for your utility
program.

 This is only some ideas, I've not tried this myself.  Well, except
for using PPmore.
