Menu bar IE8 client error

I have a problem at a customer with the menu bar in IE8. The customer can not open any menu item which has sub items. The items will not be shown. This is with a custom theme, but with the default theme the problem is still there. The problems is only in IE8 and I can not reproduce the problem in a test project. Has any one has this problem also? Or has someone a solution?

Please test the application with the following link. If the issue still comes up it could be a security issue for the system administrator.


And are you sure it's not a client/server cache problem?
