flexfax: faxrm -> don't have permission

[Michael Kremliovsky <mike@etecom.com>]

   Quick question,
(Linux RH 5.2, rpm installation, works great):
I'm trying to faxrm a job (as root or fax user), but it responds
with 

   504 Cannot kill job: Operation not permitted.

Any hints how to fix it?

   Thank you, Michael Kremliovsky
