In terminal do:=

sudo lsof | grep /Volumes
     (password when prompted)

This will list all the open files on the non-root partitions that are 
mounted under /Volumes.

If it shows just a few then they will indicate where to look. If 
there's lots and you have partitions other than these two, try

sudo lsof | grep "/Volumes/<thePantherPartition>"

with <thePantherPartition> replaced by whatever it's called, and 
you'll only see those on that partition. You only need the quotes if 
the name of the Panther partition has spaces or similar. If there's 
still lots, it's just a long slog through them.

For each one, or each group that seem to go together, decide if you 
should be running that thing from your Panther partition. If not 
check the equivalent place on the Tiger partition. If the object 
isn't there, copying it across may help, but if it's being accesses 
via an alias you need to find the alias. As aliases aren't a Unix 
thing I'm not familiar with how to do that, but someone else here 
might. Applescript perhaps? Anyone?
