Congrats on releasing DF4WP, looks great and I can see this integration feature being very useful.

One small niggle.

On the demo page: http://df4wp.dataaccess.com/index.php/chinook-desktop/

If you select an artist with not a lot of albums and move your icon above a grid and try to use the scroll wheel, it no longer scrolls the page. While I can understand it is useful for a grid to catch the scroll wheel, it should just pass on the scroll to the page if there's no content to be scrolled.

Another -even less serious - issue is that the font is dropping parts of it, making it hard to read
