Running Joomla 1.5, ari menu vertical, problem in IE9.

The page is here: 97.65.85.25

The menu is appearing fine in all browsers except IE9. In IE9 a strange problem occurs that seems to have something to do with 3rd level sub menus interacting with 2nd level sub menus, CSS style appear to be applied incorrectly and menu labels are erased. I'm unable to find any pattern yet except that the errors only occur in menus with three levels. The error only occurs on first page load and the menu appears properly after rolling over a menu item with the mouse.

The problem is obvious by visiting the above link or attached in the image below.

Just wondering if anyone else had experienced this problem or have any ideas as to how it may be resolved.

Thanks

Hello,

The menu looks normal in IE 9:
