No, there's no list of sites where the Google toolbar pop-up blocker has
blocked pop-ups. They are all blocked. There's only the "whitelist" - site
where you *allow* pop-ups. If you reset the counter, only the counter gets
reset, your "whitelist" remains intact. The counter info and the
"whitelist" site list is stored in the registry. You can tell when the
Google toolbar is blocking a pop-up as your cursor will change briefly to a
hand with a red and yellow starburst on it with a exclamation point in it,
and the pop-up icon on the toolbar will show a red/yellow circle with an
exclamation point in it as well.
The information I pointed you to is contained in the Windows Registry. This
is the main core instruction set for Windows and all your programs. You can
access it by going to Start...Run...type in "regedit" (no quotes), click
Okay. But I would *strongly* advise not messing around in there if you
don't know what you are doing, as a mistake there can cause errors, up to
causing your computer to not boot.
