Thanks for your reply. I have actually solved the problem (at least temporarily) - I added some margin to the left of the top menu, which now forces it underneath the search bar
Here's the url anyway (if you can suggest a better way to fix it). http://bnes1-n2s.hosting-services.net.au/~abundan1/life-journey/
I actually wanted another module showing that position (as you will see) but was surprised when even the menu itself didn't show up in the correct position. It appears as if the menu only gets "pushed" into the correct position, and not actually forced into the correct position...
