How Did I Miss This? IE Automatic Component Activation Will Revert to Old Behavior
Hallelujah. Bravo Microsoft! I really don’t like using JS to embed Flash into a page, so this is good news for me. No more SWFObject for me 
Don’t get me wrong, SWFObject is a great piece of code. I just hate having to think about Flash at all. Unless there’s actual communication between the SWF and the page, I just want to dump it into the doc like any other element and be done with it. I can’t tell you how many problems I’ve had over the past year with Flash and JS embed techniques and bizarre bugs… Pain. Great pain.
IE Automatic Component Activation (Changes to IE ActiveX Update)
Back in April 2006, we made a change to how Internet Explorer handled embedded controls used on some webpages. Some sites required users to “click to activate” before they could interact with the control. Microsoft has now licensed the technologies from Eolas, removing the “click to activate” requirement in Internet Explorer. Because of this, we’re removing the “click to activate” behavior from Internet Explorer!
It’s important (and cool) to note that this change will require no modifications to existing webpages, and no new actions for developers creating new pages. We are simply reverting to the old behavior. Once Internet Explorer is updated, all pages that currently require “click to activate” will no longer require the control to be activated. They’ll just work.
