Quero Toolbar IE add-on
Due to a patent dispute between Microsoft and Eolas Technologies who claims having "invented" the idea of embedding external program objects into hypermedia documents, now users have to activate Flash animations, video clips or Java applets with an unnecessary extra click. The ActiveX update causing this change was included in the last cumulative security update MS06-013 which was released on April 11. Fortunately, Web publishers can update their Web sites to avoid the activation. Basically, the objects need to be created in an external Java script to workaround the activation. More information about possible workarounds is provided in the MSDN article Activating ActiveX Controls.
