Thanks, fishin'!
It might well be that I clicked on something in another (registry) program, (like "start scandisc always ...."). [Grrrrr!

I'm going to look for that properly ... after having followed your advice. :wink:
(I suspect, however, that it is, because I'v installed "weather watcher", with automatic refreshing of the site/wallpaper every 5 mins on that drive.)
