A couple months ago my news provider, NewsGuy, changed the way they number the articles. Since then my news reader, Agent 6.0
has been very slow in retrieving new headers.

NewsGuy support says I should be getting headers as fast as I was before their change. Agent support says as long as I have
certain settings set the way I do then it isn't Agent's fault.

So the only way to sort this out is to try a different news reader. What recommendations do you have?

I had that problem with v1.93. OnlineCatch Up With Selected Groups
fixed it. You have to do that every couple week or so.
Think I purged newsgroups too.
It resets a couple files keeping track of header numbers.
Funny thing is with my new computer I don't have to do it.
Probably something to do with how it handles memory.
Don't know if v6.0 uses the same scheme as v1.93, but it's a good bet
it does.
