In a square image, make a circle with the Shape tool.
With the Text tool, start adding short, center justified text in a new Text layer.
Go to the MOVE tool to adjust the vertical placement, and find the Text has somehow become related to the circle, because a UI ghost of the circle follows the Text as you move it. (Plus, a second go at it puts text around the circle. !?!?!?)
Really I just want the text layer to be completely oblivious to the Shape layer.
When did this change, and how do I get it to stop?
"Putting the HARM in 'harmonica' since 2005."
With your text tool, be sure to click outside the confines of the circle shape. Clicking inside will give you text-in-a-shape (your text cursor will display a small circle around the I-bar before you click), and clicking on the edge of the shape will give you text-on-a-path (I-bar with little squiggle behind it). If you don't want to worry about where you click, lock the Shape layer first.
It is easier to destroy than to create.
More fun, too.
