Menu doesn´t work in IE 8

[Diego Arena]

Hello:

I created an web application using a menu. The problem that I am
experimenting is that when I put the mouse over the menu the option list are
no displayed  in IE8. In Firefox it is working fine.

This is my menu class:

public class MainMenu extends Page{
  @Bindable
    protected Menu rootMenu = new MenuFactory().getRootMenu();

    public MainMenu() {
        rootMenu.setStyle("color", "red");
    }

}

I don´t know what is the problem. If any have an idea, please let me know
what is happening.


Thanks

Diego
