can't close file
Running InDesign CC 17 (220.127.116.11). Having to quit app every time I want to close a file. When trying to close file, application frame remains, but I can not close it or minimize it, or open other files. Am quitting app every time I need to open a new file.
Running Mojave 10.14.6
clicking x in red close button nor CMD-W -- neither work correctly nor immediately.
but when I clicked About indesign the frame closed. WTH?
