Hi, these problems are present in both v3.0.5 and v3.0.6 running on both XP Media Center SP3 and XP Pro SP3.

1. Using any standard MDI application, such as Excel 2003, it is impossible to dock the child windows at the corners of the parent window. When you drop the child window near the top left corner of the parent window, the child snaps to the left edge correctly but it does not snap to the top edge -- instead it snaps about 110px below the top edge. If you try to dock to the top right corner then it snaps too low (110px) and too far right (about 2px). If you try to dock with the bottom corners then it snaps too low (about 110px).

2. Child windows do not snap to the edges of adjacent child windows. Not sure if this is actually a supported feature, but if it is then it's not working with MDI windows.
