Before the update, I was able to double-click on a corner or middle point of a text block and it would snap it to a smaller size to fit the text. After the update, I'm not able to do that, and I can seem to find where I can turn that on. I've tried right-click, Fit to Content, but it isn't doing anything.
It is still working for me in 2023. Be sure that the tip of the mouse pointer is located directly over a handle before you double click. Also, show Hidden Characters to make sure there aren't ¶¶¶s keeping it from tightening up to the text.
Thanks for checking in! It only seems to be on some text blocks, so I'm still not sure what the problem is. As a follow-up to the previous responses, this is a layout template that I regularly use, about 40 times a month, so believe me that I have tried all the usual solutions. I know where to click, and I've checked for hidden characters. I usually do import my preferences so that I don't have to re-create my workspace each time InDesign updates, but for some reason, my preferences and my workspaces (in every Adobe program) did NOT carry over this time.
