Depends on the URL you're at. If you visit:
www.kryptronic.com/DEVEL/store/public/
That's ClickCartPro pulling in the Joomla! template as it's skin. You're actually looking at ClickCartPro here.
If you visit:
www.kryptronic.com/DEVEL/joomla
That's Joomla! pulling in the ClickCartPro skin widgets into it's menu. You're actually looking at Joomla! here.
You can bounce back and forth between them. I set up the ClickCartPro menus so they all appear in the left navigation column and the Joomla! menus are all in the right navigation column. Single-Sign-On is enabled so once you log into one, you'll be logged into the other, and all changes will sync.
