I am doing a new look website for wheelchair football. I created a navagation menu using Vista buttons, but the swf flash file I was using under the menu bar was blocking out the sub menus. On Vista Buttons FAQ they give a solution of adding "opaque" parameter for <object> and <embed> tags. This solved the problem when viewed in Firefox but when I view it in Explorer the menu bar is still being blocked by the flash file. Any ideas around this please ?
