I just installed Windows 7 and purchased and installed Object Desktop. For now, I'm wanting to modify the Windows default Aero theme.

Here are the problems I'm having: 

1.  I can't find the Windows 7 default Aero theme (skin?). WB7 is only showing Diamond (with the Stardock start button).

2.  After I applied the Diamond theme, I wanted to get back to my default Windows 7 Aero them, but it seems that the only way to do this is through the Theme Manager. That doesn't make any sense to me. Why can't I control this through WB7

3. How do I actually install new skins (.WBA) files through WB7? When I point WB7 to a .WBA file, nothing happens ("Install New" under "Skin Options"). It never shows up in WB7.

Thanks
