VIEW problem

I use Windows XP Pro, Internet Explorer, but mostly Firebird.

When I go to the Microsoft Newsgroups and want to see any replies to a
question which I posted and select the above, I get in red first quickly the
responses, but then quickly thereafter all responses in black, that have
nothing to do with my question. In other words, responses to someone else's
question.

That is not the same in all newsgroups. In this one it showed only the red
ones (to my questions) but in most others it shows both. Very annoying when
one is in a hurry.

In previous years I never had this problem, not even with Windows ME.

What causes this now?
