Internet Explorer (and possibly every other browser including Firefox and Opera is about to become a lot more annoying. Apparently a company called Eolas has a patent on browsers with plug-ins. Or to be more precise they have a patent on:
“Distributed hypermedia method for automatically invoking external application providing interaction and display of embedded objects within a hypermedia document”
The result is Microsoft having to come up with a way round it to avoid paying license fees. Any plug-in content on a web page (Flash, Shockwave, the dodgy XForms support or any ActiveX control) will have to be explicitly activated before you can interact with it. In most circumstances this isn’t so bad - except for those annoying floating ads: you’ll have to click them twice to get them to go away.
If you have automatic Windows update, you’ll get it on April 11th as a critical update. Wikipedia article.
