Works Well – But no WYSIWYG when editing page

This columns program works well, but does not provide wysiwyg verification for the 2nd (of two) columns when editing a page. I use Text Editor rather than Visual Editor (I do understand HTML – which makes that easier) and then keep a copy of my website open in a separate tab, refreshing it as I Update in the editor to make sure things look as I planned. So far that works fine for me, but I’m sorry to say the Visual Editor looks a mess for column 2.

My webpage is http://www.bedetrial.org/
and so far I’ve used Easy Columns only on the front (home) page.

The issue described above may be because of my use of images and tables within the 2nd column (which appears as the middle column when you take into account the sidebar on the right which appears to be a third column.)
