I noticed this strange behaviour too and wondered what was going on. To me
it seemed to happen when focus was not on the newsagent e.g. because it was
minimized. I thought it had something to do with the process priorities and
the program being too cpu intensive on my machine. So far I use NewsGrabber
and OE4 in combination.

DU-meter reads pretty stable at about 85 Kb, then for five seconds or so
goes to nearly zero and starts again.

I can't find any configuration options in these programs to prevent it, but
NG says I make two connections even though I only download one article at a
time. And it shows one connections even when I don't download anything.
I understand you see one connection only?
Maybe NewsGrabber is rotten in some way.
Funny though i used to get about 100Kb/s from stofanews with the same
program when their server worked.

Do you know if the same problem exists with Forte Agent or SuckTheBest ? Or
is there any way I can know which commands my software sends so I can go
look for a better application?

What do you mean by 'properly tuned'? I've set the DefaultRCWindow to 48K
something in Windows registry. Isn't that The performance tweak for windows
machines?

Of course that's non-sense, but for some odd reason NewsGrabber won't even
start downloading if I allow one session only. That program seems quite
suspect I think...
>Hope this info is useful somehow...
Sure it is! I would really like to solve this mystery, too.
