When this icon appears it disallows many functions within Creo Illustrate. Anyone know what it means?

Did you ever determine what this icon was? I too am experiencing it when trying to transform some objects in Creo illustrate 4.1. I haven't been able to figure out what's causing it, or how to let it allow me to transform.
Your smart filter is on in the lower right.
