Sounds good.

I did wonder why you would get the UAC alert at different times, instead of all the time. (and vice-versa) But you already gave that answer, by stating you had Ghost. You left me scratching my head a few times, but it's clear to me now.

OK here's a site that initiates the behavior I am referring to.  I visited the site 4 times in about two minutes, closing the new window each time.

http://bfc.positscience.com/eval/bst.php

The first two times I visited it, UAC popped up an alert, with no usable details.  I denied it both times.  The 3rd and 4th time it just gave the Information Bar, asking if I want to install Shockwave.  And the UAC alert no longer comes up, even though I denied it both times it did come up.

Here's what I got from the page you sent me to. I visited the page in IE7:

I did get a popup asking permission to install a component. It's from Adobe Shockwave, but the component that asks to be installed is called zest_sweep, from the publisher Posit Science. It claims to "Add functionality to your computer to generate specific sounds."

I can only conclude that the "Brain test" uses sounds specific only to this website, since Windows already has built-in sounds , but your computer cannot generate these for this test without this add-on.

I can only give you two solutions. 1. Is to install this component if you frequently visit this website and use their services. Or 2. If this is a site that you ran across randomly and don't plan on returning, don't install it. The reason is simple. The less your computer has installed, the happier you & your computer will be.

My point of view may vary from person to person, but it all boils down to the fact that if you don't plan on returning to the website again, don't install any add-ons, and just move along. Unless you see and understand the code that the website wants to install, it's hard to trust anybody (or websites) anymore. I'm sure you've seen the damage from other users' computers, by the HiJackThis logs that Richie has to help with.

My interest is not in the site, but rather in the inconsistent behavior from UAC. 

OK I'll just chalk it up as another MS anomaly. 

Thanks for the help.  And I agree with your point of view about not installing junk.  The beauty of imaging software like Ghost is that you can always go back to a clean state.

By the way, how did you find out the name of the component it was trying to install?

Ahhh, ancient Chinese secret!

Actually, it's quite simple. If you visit a website that requires a specific bit of code to run, and you don't already have it on your machine, this is where you get a Windows popup (or alert) asking for permission to install or run. I'm not going to get into details on how Windows goes about checking what plugins and add-ons you have installed because that would be a whole other discussion, but it is all determined locally on your machine what you have, and what you don't have to make the website work, by the code in the page you're viewing.

Interestingly enough, I just now checked that website with my XP Pro machine, (using Firefox and a multitude of add-ons) and I still get the same alert (with the same information) as I did with my laptop running Home Premium.
