I have been consistantly updating my Shockwave and Flash plugins everytime one comes out, and each one was better than the last. I'm not sure what kind of set ya'll have, but man...

As for not getting it to install into Mozilla or Netscape 4.8, simply just take the "NP-PPC-Dir-Shockwave" file from the plugin folder of Netscape 7 or IE and just copy it into your plugin folder on whatever browser you choose.

As for the "Shockwave tuner", it's always at 8.5, that hasn't changed for a while now...and the update doesn't state that you're getting a new version of the tuner, just the actual plugin.

If you're having issues, try the suggested runthrough over in the help section of Macromedia. They have a little process where everything Shockwave(or Flash) is taken off your Mac, then you can try to install again. I've had to do it once, it was easy, after that, no more problems.
