Right Hand Side (Places List)
Remember for a Vista/Win7 skin, you need to set your bottom text margins to a neg. value (around -35 or -40 is what I use as a default). Without it, items on the bottom will get chopped off when there is a lot of content.
Also important to note, is the top text margin and this applies only to a Win7 skin:
User Pic Location
The area normally occupied by the user pic is 40 pixels high. If the top part of the start panel is f.e.x 10 px high, you need to set your top text margin on THE RIGHT SIDE SECTION to 30px. This applies even when you have the user pic hidden.
