Vista - newsgroup shows incorrect unread count

I've had this problem with XP/OE and it seems to exist with a new install of
Vista/Windows Mail.

After a while, a newsgroup starts showing an unread count when it shouldn't.
For example, at the
moment, m.p.vc.ide.general shows that I have 3 unread . When I select it,
no posts show up.
If I do "catch up" from the right click menu, it clears but it comes back
next time I select the group.

It seems that this happens after running the automatic "Windows mail can
optimize..." thing.

A second thing is that "catch up" seems to take a lot longer after running
this optimize. Clicking
on a message, doing a select all, and then mark as read works immediately.
This also existed
with XP pro.

Is there any way to reset whatever is causing this?

where nnn is usually 300, to make sure you have downloaded all the
messages the newsgroup offers.

Actually, I first noticed it on comp.lang.c++ and I still see the problem
with that group at times. It has been just recently that I've seen it
with the MS groups. And then it's mostly been m.p.vc.ide_general
and not the others that I monitor (mostly vc related groups until my
recent Vista upgrade)
