I ran you ASkinDemo (version 7.2) on both an XP machine and Windows 7 machine and both exhibited the same problem with listview. When you run the mouse over the listview some of the horizontal grid lines disappear.
Also, the magnifying glass still exhibits problems when using Windows 7.
I use both the listview and the magnifying glass in my projects along with many of your other components and need nearly flawless behavior (over 2500 users). I love your version 7x, but until most of these bugs are solved I will have to stick with version 6x.
