Hey babyoh, SpyDie and ripley!
Thanks for your comments. You know, this problem may actually have nothing to do with my recent updates. It's just that they're the only significant changes I've made since I was last able to download.
babyoh, yes I am using IE 7 exclusively, at present. I've been threatening to get some other browsers, and several have been recommended. But I can't seem to build up the patience I need to learn how to use them, all their tricks and secrets, and such. Sigh....I think I may be growing resistant to change (in general), in my old age

Alas....and the heat of summer, when it doesn't cool off enough to sleep until 3 am, and 10 minutes after your shower you wonder why you even bothered

.....just doesn't inspire much patience, ya know?
Oops, anyway, getting back to the topic -- I have also thought about switching firewalls as a troubleshooting step. My firewall
has caused trouble in the past (not necessarily with downloading). But since mine doesn't get updates, it doesn't seem to be a likely culprit, in this case. Nevertheless, I'll try the switch right after I post this reply.
Oh yes, I'm quite familiar with IE 7's security settings. Even though I haven't made any recent changes, I did look to make sure there hasn't been an inadvertent change. "File download" is set to "Enable". So all is well there.
Ah SpyDie, I so treasure your longs shots, hunches and such

! Even if they don't solve the problem, I always learn something from them. Ok, I'm not sure if you gave me 2 different instructions for finding the same info, or if they are entirely separate things. The Value Data is "0" without the quotes. And I'll try the 2nd part.....ok, if I did it right, the results are:
! REG.EXE VERSION 3.0
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3
1803 REG_DWORD 0x3
What's it mean?
ripley, yes I'm aware of the changes to the security zone settings brought about by IE 7. I recently discussed this in a topic at the CoU forums
[here]. I guess it's a little bit off the subject, but the thread contains a good bunch of resources for potential future readers. And the simulation to which you linked, will make a nice addition to that collection

Unfortunately, I don't think any of those new settings are part of this problem, because I had not changed them prior to my trouble downloading. Nor had I changed any of the Advanced settings. The current configuration permitted downloads, before.
System restore may well be my best option....but not a long-term fix. Because won't I still have to go back and get my Windows updates? Or could the updates have somehow become corrupt? Meaning that Restore, and re-Update might solve this problem?
I'm still stumped!

Thanks again for everyone's comments
