Annoying screen message

I recently upgraded from Coreldraw 12 to X4. I have an old document created in CD12 that I've copied some diagrams into a new document in X4. But at the centre of each diagram I'm seeing an annoying system message that says "Click here with text tool to add paragraph text." I've looked at it with wireframe and I don't see anything that suggests it wants paragraph text. The message is not text or an object; that is, I can't select it. I never saw this in CD12. How can I get rid of this message? It's really annoying. Thanks.
