RootkitHunter specific tests not running

[les.etincelles () gmail com]

Greetings everyone,

this is my first post to this forum, although i have been following the lists for a while now in the hopes of 
complementing my training as a sysadmin.  so hello there!!

my question relates to Rootkithunter, 
http://www.rootkit.nl/projects/rootkit_hunter.html

i am using version 1.3.2, the latest release.  my machine is an older ibm thinkpad running PCLinuxOS 2007 which is 
based on Mandriva with KDE.  

After performing a couple of system scans, I noticed the scan logged that it did not perform a couple of checks, 
specifically the "hidden processes" check.  saying that this test was skipped via user's request.  

upon looking into the configuration file /etc/rkhunter.config i noticed that it states its default is to perform ALL 
tests and disable NONE
however i noticed there were a couple of tests listed as disabled.  i then proceeded to edit the file in vi, changing 
the disabled tests field to "none"

i then ran another scan, and found that the hidden processes check is STILL not running, it is still being skipped.  if 
anyone has any insight as to why this is happening, please post.  i am preliminarily thinking it may have something to 
do with the way this particular linux distro is laid out? thx in advance.
