I've created a Zen sub theme using the Starter Kit enabled it, and set it as the default (I've changed very little from the Starter Kit). If I go to Structure > Blocks there is only a tab for the Zen theme (which is enabled, but not set to default). I can set blocks into different regions and save, but the changes are not reflected on the page. If I switch to the base Zen theme, the changes are there, but switching back to my sub theme shows just the default layout.
I'm new to Drupal, so should the sub theme be inheriting the base Zen theme's settings, or should there be a separate tab for the sub theme? And what do I need to do get the tab to show up? I've gone through numerous examples and tutorials without finding an answer.
