I couldn't get this to work for Nodes that are set a tabs on the main_nav menu (I have the Nodes as Tabs installed).
I have several Nodes as Links setup under a single category. If I navigate directly to that category and click on the links, they now open in a new tab window. However, If I use the menu item that I've setup for all the links in that category, they still open in same window.
How do I control open in a new tab from the menu items?
Ugh, should I be asking this in the Nodes as Tabs forum?
