This will affect any item on your web site that uses the   Microsoft ActiveX controls loaded by the APPLET, EMBED or OBJECT methods. Some   widely used applications that use ActiveX controls within the browser include   Adobe's Reader and Flash, Apple's   QuickTime   Player, Microsoft's Windows Media Player,   RealNetworks' RealPlayer and Sun's JVM (Java Virtual   Machine).
              What does this mean? 
              An example would be that you have a brief Flash movie, say on your home   page or wherever. At the end of a brief presentation, your viewer may be given   some choices to click on. With the new update, the brief presentation in the   beginning will play as normal, but before you click on one of the links at the   end, you will need to “Activate” it by either clicking anywhere on the movie, or   if you mouse over the movie, a border will appear around it and the instructions   will pop up to either click on it or press the spacebar or hit enter. A simple   enough task, but may be confusing to some people, especially in the beginning   and through the next 3-6 months as when they click something, at first, nothing   would happen. It’s the second click that something would happen. This is   especially hard hitting if you have a Flash banner advertisement somewhere. 
              Why is this happening?
              According to e-Week, “... the IE update, which results from a   multimillion-dollar patent spat with Eolas Technologies”. You can read more   about this from the following e-Week articles;
              "Microsoft Delays IE's ActiveX D-Day" (http://www.eweek.com/article2/0,1895,1943847,00.asp)
              Is there a solution?
              Grant Communications LLC  has been studying several papers from   Microsoft on workarounds. We will be testing them in the next week. The fix to   implement does not appear overly difficult, and uses an external Javascript file   to “write in” the HTML code currently present on the page in plain HTML.
