if you go down to the very bottom of any screen, there is a box that shows ---Aqua Vision4. if you click (or tap) that, it has a dropdown menu where you can select our mobile style --Default Mobile Style. See if that helps for navigation.
the only reason we don't have that on by default is because you will lose features such as images and stuff, so we've left it as a full-access site. but if you're having trouble, try switching that over. you can always switch back.
