Well, that was easy!
I just upgraded to MT 4.12. Just like that. And because I got tired of that broken layout, I changed layout. Easy peasy. I'd rather just have two columns, but mostly I'm glad not to have my column at the bottom of the page.
I might change styles again, but at least this works.

I like the new layout, the colors are awesome :-)
