Just tested the gadget on windows 8 x86 customer review edition, and it seems to work even better than in windows 7 for some strange reason. To clarify... during a windows 7 installation of the gadget, it seems that you need to restart the Sidebar to see the gadget for the first time, but only the first time. I haven't been able to figure out why it does that yet. However, during a windows 8 installation of the gadget, it seems to start up right away after installation. Im pleased about that at least.
