Here's a couple of pictures, one showing the "classic" List View control (with the solid dark blue highlighting), and one showing the Windows 7 style (the light blue highlighting, plus the even lighter hover highlighting). It's really not that much of a difference, it would just look more like Windows Explorer.
(I'm not quite sure how to show attached pictures yet, but they should be in the attachments; please let me know if they're not attached correctly.)
And thanks for the quick reply!!
