I normally use Firefox (currently 18.0.2), but I just tested in IE 9, on Windows 7, and the share button works just fine for me.
I don't use IE enough anymore to know all the latest bells and whistles. In Firefox/Mozilla there is an option to start with all add-ons disabled, to facilitate troubleshooting. Perhaps one of the resident IE experts can advise you better.
