Hello again, and thanks for all your replies!
So very few of you use Live mail? No wonder, the wonder is why microsoft invented that program.... but anyhow I dont dare to go back to old windows mail, for fear of things going wrong in the proces.
DJ Bone:
I use Win 7, 64 bit SP1
Avast Pro
Latest program version
Spywareblaster installed, use windows firewall.
Charyb:
I use a pop3 protocol.
My inbox contains 4000 emails (few of them have big attachments)
I only have one account (well two, but in reality they are the same, they just have diffent names)
I was not aware I was subscribed to RRS (had 54 unread messages there), I have now deleted all and unsubscribed from all.
No newsgroups as far as I can tell, I dont know where to look, but since I have never used them, I suppose there aren´t any.
So as it is now, it function as it should - BUT whitout the mail shield activated, which I understand is not a good idea security wise. If I turn it on, it takes 10-20 sec. to open each mail.
