Since you guys are talking about start menu margins, here goes two tips:
* For Vista and Windows 7 start menu (do not use it on XP):
Set the Start menu right side bottom margins to -40 (minus 40), this will place the items on bottom
on the default OS position.
* For Windows 7 (only): set the start menu right side top margin to 40, this will prevent the selection
graphic from being cut, the OS (Windows 7) reserves this 40 pixels on top for the user icon and places icons.
* Important: do not use these tips above on XP, will not work.
