Opacity 0 does not hide elements on load of app

This is a bug that is only happening on windows xp (I am testing on WinXP Pro), it works fine in Windows Vista & 7.

What is supposed to happen:
When the index page loads, seven divs are loaded on screen, but all except one have an opacity of 0. User clicks on menu item, which will cause the corresponding div to change it’s opacity to 1 and all others to be 0.

What happens:
When the index page loads, all seven divs have opacity of 1 (so all divs are visible). When the user clicks on the menu items, it functions as it should and only one div becomes visible.

If needed I can upload screenshots or PM code.


It probably depends on which Internet Explorer version is installed on your XP.
