BillD, I haven't checked this for a while. Thanks for the information--I've added several extensions to play with. I looked in IE under "Tools" and "Managed Add-ons" and found quite a few there. Big programs that linked themselves to IE.
John, as usual, thanks for the updates. Interesting stuff. I guess whoever stole my old HP with Win2000 will have to think of something new pretty soon. Just don't come looking here again--I now have bars on the door, finished installing the decorative iron over the windows, and have a dog in the back yard. All low-tech "updates" in response to computer crime. (The dog is a Staffordshire Terrier, AKA pitbull, a stray who wandered in injured, but now that she's recovered she's such a sweetheart our only hope is that her barks will scare people off before they come through the gate and find out she's found another long-lost friend. . .)
