I realize about the small icons, the only thing I have on my start menu is computer and control panel and still the start menu is larger.
i edit the skin in skinstudio and it shows that the start menu looks small and I save it as a substyle. when i apply it, looks the same as if i hadn't resized it. tried reloading wb as well.
It has nothing to do with editing in skinstudio, you say you only have computer and control panel on start menu, that is on the places (right) side, how many programs do you have on the programs (left) side. You must decrease number of items on this side as well in order to shorten the start menu.
