Internet Explorer 9 platform preview 2 was released this morning
You can download it here. The IntelliPoint bug: bug ID#: 554429. If you are apart of Microsoft Connect and could take a few moments to verify the bug and vote for it, I would really appreciate it. In any case, the platform preview 2 seems to be a lot faster. They still haven’t updated the UI to include back and forward buttons or even an address bar. Anyways give it a try.
