Using template Enterprise gives me some stylingproblems (or a bug?) for the tablet-view.
See, for example, http://cbko.alstest.nl/bij-en-nascholingen/de-dorn-methode/dorn-algemeen (on tablet! portraitview).

The navigation is still beside the main content, not stacked above or beneath the content. But it is too long now; the bottom-side of the site is not correct. (Layout and styling are as my customer wants it.)
How to solve this?

Another problem: if I choose, in template setting, for ‘Sidecolumn After Component’, the sidecolumn moves to the right (after scrolling), not to the bottom. As seen on iPad-3 and some other tablets.
Can I force the sidecolumn to move to above or beneath the main content? Maybe with altering the breakpoints in responsive.css? I don’t know how!
