I just installed IE9 on 64-bit Windows 7, and I've pinned DaniWeb to my task bar. But the IE9 icon just looks like the standard IE letter 'e'. I read that we need a special *.ico file, see this link

Does anyone know anything about this, because I sure don't.

I think the size of the available .ico file doesn't meet the requirements for IE9 pinned website icon size as explained in this link you should have 24x24 sized .ico file if you don't have you can also create your own .ico file
