Both a hot fix and tech note for Flex 1.5 were issued today, addressing recent updates to the way active content is accessed in Microsoft Internet Explorer. An excerpt from the technote (links to the hot fix downloads can be found within the full technote, of course):
“Microsoft’s update to Internet Explorer was published on February 28, 2006. This update changes how Internet Explorer handles some web pages that use ActiveX controls. Certain web pages, including the default Flex wrapper page for Flash Player, may require users to manually activate ActiveX controls by clicking on the control or using the TAB key and ENTER key.
