[OS X TeX] TexShop Pref re console not working/sticking

[Peter Teeson]

OS X 10.8.5 Mountain Lion, MacTex 2013 May 30 package.

There is a TeXShop 3.26 preference to set the Console to only show on error.
I changed the default setting from "always"  to "show only on error" but the console always appears.
This is even after I have closed that window.

What could I be doing wrong?

Thanks

Peter
