I've been using the code from http://freshinbox.com/blog/hybrid-collapsible-menu-for-email/ to create hamburger menu's for a while now and it always worked fine.

However the latest Outlook.com app update seems to break it. Instead of showing the fallback navigation I set, it shows the one that is only suppose to render on webkit, but instead of working it shows the 2 hamburger images AND a dropped down version of the navigation.

Anyone any idea how I can at least remove the hamburger images? I can live with the dropdown showing.

thanks, Lein
