I am using OUtlook Express and Windows XP.  How do I delete old headers 
from newsgroups?  I have tried using the Tools, Options, Maintenance but for 
some reason it does not work.  I still have headers from 2 moths ago that I 
have to sort through.  I used to have Win Millinium (that's right, I was one 
of, like 3 people to have bought it), and I used to got thru Windows 
Eplorerer, Outlook, Identities and just erase the newsgroups from there. 
For some reason, I can not find those files in XP.

Help!
