Hi tgreen80…first, sorry for late reply but for some reason your post did not show here for me earlier today, but just now seeing it. Anyway, to help you out here, I should mention that as far as I know, ie10 is not official yet except for those on Windows 8. However, let’s figure this out and see if I can find a solution.
First up, make sure you create a menu and not to use the default menu that shows on first install because that is a “Fallback” menu and it’s not fully styled. The idea is to create your primary menu:

for adjusting when the menu goes into the mobile menu, give me a bit here to try a couple things on my local site to make sure it will be ok.
