Following update of OS to Monterey 12.0.1 and using InDesign 2022 17.0.1, opening files that had been previously created, when editing text within text boxes, as soon as I click elsewhere then the text within the box vanishes - as thought there's not enough room for it, when there is.
Sometimes clicking back on it causes it to reappear, sometimes the box just won't return as a visible element.
