InDesign 20.2 Mac M1 Sequoia 15.4.1. When I click a text box to select it, nothing happens until I jiggle the mouse. When this happens the corner boxes appear. However, many times when I click, nothing appears selected. This bug is unsettling. This is why I prefer to use InDesign 19 for important jobs. The text block in the attached screen shot has been single clicked.
