some users act differfently

[Jean-Pierre Radley]

Users run filePro on a Unix server, connecting via ssh under Anzio.

In a certain input processing, there is a choice to mail an invoice.
This works fine for all  but two users.

These two users get hung up in filePro after electing to Send, unable
go close the screen (DelDel just prints a non-ascii character to the
screen).

I see nothing special in their .profile files.  I can log in and su to
either of those users and get similarly stuck.

The process table shows the mail commands launched by a SYSTEM call, and
I have to kill them manually.

What could cause hang-ups from a filePro SYSTEM command only for certain
users?
