Unknown process accessing INBOX

[Tom <tommyr agora rdrop com>]

I moved my system to a larger hard drive after repeated crashes.  Root can
access the INBOX but all other users are dropped into a READ ONLY mode
when attempting to access their INBOX.

	"Mailbox is open by another process, access is readonly"

I can't seem to find where the lockfile is located nor the process that
has the mailbox open.  Any ideas?

Thanks
