Issue with Upfront + Floating region + moving/ scaling elements within

Hi,
Im using the upfront theme for my site. I am trying to setup a floating sub-menu that is fixed below the main floating menu. so that i can use a combination of icons(embeded anchors-allready done) with text titles for each.

When i try to edit the size of the containers to something smaller so that i can fit them closer together they keep expanding and becoming very hard to adjust the way i need them. is this a bug or is there a special technique to doing this? - finding it very fustrating spent close to 40 mins trying to move these arround to get something suposibly simple. but as you can see all i get is mess. - Screencast http://take.ms/pMEHH
