I am using the superfish menu for pages. The menu for subpages is not displaying right in IE7.
I had a problem in firefox but added repeat-x to the menu_right_over.gif and that fixed a transparent area in part of the box.
In IE7 the subpage menu, the dropdowns are displaying behind the page content below the main menu. see it here www.cookingsalmon.net, the dropdown menu is under Articles.
