All of a sudden, every image I open today has this 'Captain Hook' navigational symbol that pops up and stays centered on my images, I have no idea what triggered this to start appearing and nothing I do gets rid of it, not the esc. key, nothing. I request help with this as it has stopped my workflow today.
It's the rotate canvas tool. It's found in the layer's panel, nestled in under the hand tool. You may have turned it on by accident, with a gesture, in which case, go to Preferences > Tools > uncheck Enable Gestures.
