Ah the mysteries of the internet!
Guess what? The problem somehow fixed itself a couple of days ago. After endless problems, warning messages (from Trend & Windows), much reading of online "help" (?) info & a visit to my tech help planned, suddenly it all comes good!
So what was that all about then?
But now I'm getting a message (when I first turn on my computer, not log onto the internet) that a "serious error" has occurred & do I want to report it to Windows?
<sigh> No, I don't want to.
Not just now, anyway.
Give me a break!
