NPC interaction with MI3 Interface?

So I'm finally at the point where I'm adding in my NPC(s) and though they are showing up and behaving properly, I find that my player is unable to interact with them. The game was built using the MI3 Interface system from the tutorial on this site. I suspect I'm missing something obvious, but I've been working on a solution for over an hour now... Note from the image below, the cursor interaction with an object on the left side, and it fails to note that it is over the NPC on the right side. If the NPC was a scene object I would immediately realize that I had failed to setup an "object area" border for it, but NPCs don't use those... Any help would be appreciated.

Have you checked that you have enabled "command can be used on > characters or objects and characters" via the command properties tab? (for each button/command that can interact with characters).

Under the coin interface, the button titled "Default Action" was the only one that was not enabled to interact with "objects and characters". I checked that box and the problem is solved. Always a big help AFRLme, thank you.
