[Slate] MenuBar Section creating big gaps

Me again!

I’m still working on moving my beta slate widget to the new release, and I’ve got everything showing up, but my menu bar’s looking a bit weird.

I haven’t changed anything, is there something I need to define in terms of my style or something to get it to shrink back down again?

Thanks.

(Ignore the funny colours, that’s just for testing.)

Can you pastebin the code for your menu generator?

Sure, here it is: http://pastebin.com/y0qCtPiS
