Flashblock works fine. In fact, I discovered Flashblock when using Diablo, and I've never run it with other versions of OS2008.

But let me add this: The fact that there are many, many users who are convinced that this or that doesn't work with Diablo and have been unable to find solutions must mean something. I think it means that support for tablets isn't as effective as it needs to be. Maybe exhorting users to SEARCH! isn't the ultimate solution after all, because many users are giving up.
