When I "Pin to Taskbar" the WS7 application something weird happens... When I start the WS7 application it creates an additional icon on the taskbar that appears to represent the running instance of the app. That is, after clicking the icon on the taskbar to start, when the application starts an additional icon appears.

Is this a known issue? If not, how do I go about "offically" reporting this issue?

There are also several over oddities of how the application interacts with the taskbar icon - more on this later

Thanks in advance.
