http://blogs.msdn.com/ie/archive/2007/11/08/ie-automatic-component-activation-changes-to-ie-activex-update.aspxRemember that 2 years ago MS pushed out some updates... then you suddenly found your Flash not working until you click on it?
Now, it's going to change. Those who want a preview, get it from MSDC (Microsoft Download Centre).
Those who doesn't want, you can wait till 2008, but I think by then IE8 may be out.
Off topic, this lawsuit is the craziest thing on earth. A lot of browsers used the same methods to render the Flash movies embedded... yet they don't get sued... only MS get sued...
