[Pan-users] How to stop downloading read articles overview on group open

[DC]

Can someone please tell me how to prevent Pan from retrieving article 
headers for read articles?  This is costing me huge amounts of 
bandwidth.  I cannot find an option to turn it off.

I marked all of my subscribed groups as read and when I open a group, it 
starts downloading everything as if this was the first time I loaded the 
group.

I noted that my ~/.pan directory was balooning to over 200MB in size. 
Lo and behold, it would appear that Pan saves headers by default.  This 
won't do.

Here is what I would like:

I would like Pan to use a .newsrc (I've set one up, now) to keep track 
of read articles, but for it to NOT insist on downloading articles 
marked read in this .newsrc anyway.

Header storage -- I would like to turn this off.  Please point me to the 
option that continues to elude me.

Scrolling in the header pane -- is there a way to make the mousewheel 
scroll line-by-line instead of jumping several lines at a time?  This 
could be an KDE setting, but I find that Pan leaps by a dozen lines or 
more at a time, instead of the 4 lines I've spec'd in KDE config.  Other 
apps behave normally.

(If anyone has configured their Pan to behave as close as possible to 
Xnews and wouldn't mind sharing their config with me, I would be very 
grateful.)

Thanks.
