Cannot Override No Sidebar Layout

Hi, Using the free version of Simple Catch (planning to purchase but still working on the site prototype). For default layout I've selected No Sidebar, Full Width. On a couple of pages I'm trying to override the default by selecting Right Sidebar, but those pages are still appearing with the default layout (no sidebar). If I change the default layout to Content on Left, the sidebar does show up on those pages, and I'm able to select No Sidebar for other pages. See http://arokis.gogirosites.com/blog/ On a related topic, can you advise how I can specify the layout to use for bbpress pages? Thanks, Jerry
