antispam configure buttons do not function

using: NIS 2011 v18.5.0.125  , windows XPproSP3  , OutlookExpress 6.0

 

I am unable to configure 3 of the 4 antispam options.
Using: network settings>email protection>antispam>
  When selecting the configure[+] button for each of these 3 options: address book exclusions & allowed list & blocked list - nothing happens.
  When selecting the configure[+] button for: client integration - a new window pops up with email & address book selections available. I have 'Outlook Express' and 'windows address book' selected (checked).

 

I have searched for this issue but did not find anything.
Any reasons/answers or solutions to this problem would be appreciated.
