First. thanks for your help Soybean. The problem has arisen within about the last 2 or 3 weeks. Yes, I added a utility program recently - "WinUtilities" and sure, I would like to think if I uninstalled it - poof! away would go the problem. But no, I don't think it's the cause and I have checked it several times with Avast plus other malware programs. Here's an addendum to the whole thing. With Incredimail, I have completely uninstalled it [earlier this week], downloaded a fresh copy and installed it. Everything that was on the old one is there again - addresses, in and out mail, even the junk. Now I know when you delete something it's not really gone unless you actually shred it, but I thought I'd be starting fresh with a new copy - uh uh, nope. I did the same thing with Eudora and yes, the same thing - all the old stuff back. Strange.
