What is the settings that you are using to create this menu within CSS Menu Writer? Some of the code on your pages does not seem very familiar to me so this is why I would like a reference for creating the menus in this way. If I can recreate your menus like this I will have a much better understanding of what is going on and will better be able to help you get it fixed. If you have a custom preset this would be very helpful, you can post back with a zip file if you have this.
