prefs directories with "^M" in the name

[Jon D. Slater]

Hi all,
 
I’ve read the FAQ and still don’t find this issue.
 
Configuration:
Spamassassin 3.0.4
OS:  Fedora Core 4
SPAMDOPTIONS=”-d -u spamassassin -x  -P
--virtual-config-dir=/usr/share/spamassassin/%u.prefs"
 
So, my prefs files are all being stored in /usr/share/spamassassin
 
Everything seems to be running fine.
 
When I cd into /usr/share/spamassassin and do an ‘ls’, I see:
 
members.prefs
members.prefs^M   (control M, not “^” and “M”)
 
If I remove the “^M” version, after some period of time, they come back.
 
What is creating these? And how do I fix it?
 
Thanks!
 
Jon
