10.4 iTunes update breaks visualiser plug ins?

Updated via normal Sys.Upd. method, all seemed well; now running iTunes 10.4.

I see it broke every visualizer plug in that came with iTunes except Classic visualizer and regular visualizer. Classic is from... what, 7 years ago now atleast? Telling me they made it 64 bit all along?

I am assuming all the rest are cracked because of not being 64 bit, the way new FCP-X broke all editors pricey and purchased non-64b plugins.

This is a 64 bit iTunes release is it not? Otherwise I see no reason why the other plugins I have leave the visualizer screen black and inactive (exo, discobrick, wow_lab circle, and a few others).

As well, every time I open iTunes I now get a "Discobrick 1.60 : unable to locate the <> plugin , repair permissions and retry". I see its still in the normal iTunes plugin folder however. Odd.

And finally; does anyone CONTINUE getting the 'give iTunes permission' to get incoming data/tx/feed/sources, be it Store access or podcast downloads, etc etc?

I have tried everything to stop it. I log in as a standard account user and have my security set to "set access to specific services and applications", as well as having all my Sys. Prefpanes password protected from changes.

I made a point of deleting then re-including iTunes with Allowed Permissions in the firewall to see if that would work and it doesnt; still have to enter Admin/PW each time. Very annoying... If any *^%$#^ app keeps asking such a thing even when 'cleared' by the firewall settings I have, why bother with that Security pane function at all??
