DHTML was unable to load correctly. [no voice object]

Info

Affects: Norton Personal Firewall, Norton SystemWorks, Norton Internet Security
The ad filtering element of the firewall filters the voice object and popup object of Yahoo! Chat2.0 as an ad. Read below for solution.
Why?: Bad pattern matching matches part of a js expression.
Note: If the instructions fail, or you are not a US user, skip the add yimg.com steps, and start from click "yimg.com" on the left, but clicking "(defaults)" instead.

Choose for the right instructions:

I use Norton Personal Firewall Standalone
I use Norton Internet Security
I don't use either/I still have problems

Easy, Silly, Quick solution

Disable ad blocking. Open Firewall Settings, Click "Ad Blocking" then choose "Turn Off" on the right.
This will bring back all ads, to all services where previously they got removed.
To retain ad blocking, and use chat, do the below solution and not this one.
Note: I don't recommend this unless the below proper fix fails you.

The Proper Solution

(1) Open your Firewall Settings (Probably a little globe icon).
(2) Click "Ad Blocking".
(3) Click "Configure" on the right.
(4) Click the "Advanced" button.
(5) Click "Add Site".
(6) Enter into the box "yimg.com", without the quotes.

(7) Click "OK".
(8) Click "yimg.com" on the left hand side.
(9) Select the "Ad Blocking" tab on the right.
(10) Click "Add..." under the empty, white box.
(11) Select the "Permit" option.
(12) Enter "_ad." in the box.

(13) Click "OK". Click "OK" again in next screen.
(14) Click all the "OK" buttons, and close firewall settings.
(15) In Internet Explorer go to Tools, Internet Options. Click "delete files...", tick the box, then click ok.
(16) Open Internet Explorer. Try Chat2.0. It will work!
