Hi Tim - thanks for your suggestions and I tried them all but without success;
I checked in tools, options, Maintenance, and there are no selections to
remove posts.
There are no news rules in use
I am using news.blueyonder.co.uk, but I also tried some others - it made no
difference.
I removed the newsgroup account and replaced it, no change
I tried in another identity (another user of this PC) - same problem
I created new identity in outlook (on my login) - the problem remains still,

thanks for some other ideas...

Best Regards, Martin
