As a result of settling the patent dispute with Eolas, Microsoft will be rolling out its "Click to Activate" tags from Internet Explorer 7.
"It's important (and cool) to note that this change will require no modifications to existing Web pages, and no new actions for developers creating new pages," Pete LePage, senior product manager at Microsoft, wrote in a blog post. "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."
The tags were brought in during that time that Microsoft had to deal with the patent dispute from Eolas regarding the use of ActiveX objects on a web page.
