warning! responder not found with id: cube

[mummy]

I made the mistake of using several cubes (not knowing they were tied to something else I assume). Now I have 8 messages on screen even after the cubes were removed. Nothing is working to remove this so I'm close to starting over. What happened? Is there a fix?

if you mean old console error messages, they're harmless, and you can erase them with the "CLR" (clear) button near the preview controls (or you can turn on the console and type in "clear")

as soon as you place more than one cube you get "Warning! responder not found with id: cube"

what is a responder? I can't see it in the Asset list
