I updated the theme and it fixed the issue with text not wrapping in column two. Special Recent Posts does turn out to behave non-responsively in the footer. I moved it from the the third column to the fourth and far right column and that performance is acceptable there.
I removed the plugin from column three. The text-only content in column two still crosses over into column three if you reduce the browser width. So it is not special recent posts that is the issue, but how the Enfold theme handles the width of the text in columns.
I will update the theme. But I bought Enfold in December and do not consider it old at all. Unless you know of a specific fix in the update for this issue, please continue to work on a solution for this problem.
