In a previous question I asked if Metro can span over two monitors, but seems not to be the case and it opens always on my primary monitor.
Now I pinned a Modern UI Application (Mail) to the side of my second monitor. Now I really have two problems:
When I press the WIN keyboard, Modern UI opens on the second screen (so far always on the first), but
When I go to the bottom left corner (where the start-button used to be), the Modern UI opens again on the first screen and my Mail Application pinned to the other screen is being changed to the first screen! (so pinning over multiple monitors doesn't work)
Well the Feature of pinning Applications to the side is cool, but does it really not work with two / multiple monitors?
