Since a while i found a little graphic bug on almost all skins : it's about how the Menu Item Image is displayed in the case of "Favorites".
In section "More Programs Menu" there's two sub sections: the image background and the item. In all skins the item is well displayed when you scroll "All Programs" (i mean left side and right side of it), but when you scroll the "Favorites" link, generally the right side of the item doesn't feat well with the background image.
So i discover (thanks Pixtudio and Zippo skin ) ) what is the correct setting to do : it comes with the "Content Margins" of it (sizing margins are supposed to be correct). If, for example the left content margin has to be 10, the right content margin has to be -10 (and not 5 or 10 or anything else) and with this setting the item is feating to the background image perfectly well.
Hope it will be usefull.
