The submenus are popping -2px to the left of the button on each submenu. This is happening in Firefox and IE. The only browser working correctly is Opera (which is weird

The menu is made of three images with a separater defined in the menu style as a 2px and colored white
So it appears the menus are popping off of the separator and not the image.
I've set the global _suboffsetleft _suboffsettop both to zero to no effect.
thanks for any assistance on this!
