Columns on Corporate Theme

I am wondering when the update for changing the size of columns in the corporate theme will be available, or at least if it is being worked on. Would also love to know if anyone has a quick fix for this issue.

As you can see on my site, the three columns are not sized correctly for my purposes and I can't figure out how to change their sizing. I tried changing it in the code, but it just made the third column go down to a second row.

Also wondering how progress is coming on child pages showing up in drop down menus?

Thanks,

Kristina
