Scholle, the editor of the print version of Mac 911, and I went round and round over the fact that Sherlock on her Mac displayed eight channels while my copy of Sherlock showed ten.
With an implied Dude , she wrote, “They’re totally not in my Tiger version” and, along with the suggestion that we might be using different versions of Sherlock, she enclosed a screenshot that showed those eight channels—Internet, Stocks, Movies, eBay, Flights, Dictionary, Translation, and AppleCare.

I flipped open my copy of Sherlock that was installed with Tiger and I found ten channels as I expected—everything Scholle had plus Pictures and Phone Book (both of which were grayed out). The versions were the same so… what the heck?

When confronted with such head-scratchers I do what any normal person does. I click randomly about hoping that something turns up. In this case it did.
I clicked on Apple Channels in the Collections pane and—wouldn’t you know it—the Pictures and Phone book channels disappeared. I then returned to the Toolbar entry and Sherlock insisted on showing those eight channels only—Pictures and Phone Book were gone like the wind.
What I suspect happened is this:
When I clicked on the Apple Channels entry, Sherlock made a beeline for the Web to see if Apple had updated its channels. Because the Sherlock team was undoubtedly tired of hearing how Pictures and Phone Book were on the fritz (and fixing them wasn’t high on their list of things to do), they killed them. When Sherlock checked in with HQ, it duly noted their demise and removed them from the Toolbar. There was nothing I could do—toss preferences and cache files—to bring them back.
Case closed.
