There was bound to be. I’ve noticed that if you try to resize the browser window, the sidebar floats across the main text. Also, apparently, if you’re on a different sized screen, it’s not so good. Trying to fix it now!

Okay.   It’s not yet perfect but I need to go to bed.  You should be able to at least read both columns separately whatever size your browser window is.  Plus if you’re changing the size, you get a really fun effect with the swirls!
