I cant solve this problem. If I visit my page on a desktop or iphone/ipad it works just fine, but when using a Nexus 7 the font-size is for some reason increased (I think thats the problem) causing menu items to be too big and therefor giving them a new row.This is how it looks when zooming out or on a nexus 7 (header-nav and footer-nav)
You get the same effect if I zoom out or in on a desktop, so you can test here: solitude-online.com
