The Windows Live Jewel button that is found across all Windows Live Services seems to have problems with the Internet Explorer 7 zoom functionality.

(IE7 Zoom at 50%)

When I zoomed out to 50% on IE7, the Jewel button did not scale back like the rest of the website and it was all pixelated. I hope Microsoft fixes this, although it is a minor annoyance it is still something they should look into as it developed both of these products.

Update:

This only occurs when you zoom from normal to 125% or higher and then zoom to 50%.

Another interesting thing…

When you zoom from normal (100%) to 50%, the button scales down as it should like the rest of the website. Then when you try to zoom to something more than the 100%, say 150% , the button does not scale and remains at the 50% zoom level.
