Theme SimpleNature

[Timbow]

I tested the theme and it is doing some strange things when you narrow the browser window

What is the problem?

There is something wrong with I think the overflow: declarations in the css

When I have a narrow browser window the scroll bar appears at the bottom, but when I scroll to see what is hidden it is blank. See my screenshot. The site title (#banner H1) stays centred in the window while the rest of the site elements are fixed position (which is not wrong, just odd). The original template is broken in a similar but different way - there you get no scroll bar.
