The side vertical menu works fine in Safari and Firefox. The submenus popup right where they should. In IE and Opera they pop way off to the right and down from where they should be.
Put all those submenus you have inside the script tags in the div into a data file just like the one you have for the main menu. You don't need to put in the style since that is already in the menu_data file. Just put the submenus into the file and add a drawMenus(); at the end of it, then call it right after the menu_data file and that will fix the issue.
So you'd have the calls for the milonic_src, the mmenudom, the menu_data and then menu_data_vertical or whatever you want to name that one.
