Can't drag frames (and some other items) in InDesign CC 2018
Ever since I updated to CC 2018, I will randomly be unable to perform specific dragging actions in InDesign. I can't drag content frames, only nudge them with the arrow keys. Additionally, some other items that require a dragging action are disabled. Reorganizing styles in the styles panels or TOC settings or attempting to apply a new master page by dragging does not work. However, I can rearrange the order of the panels themselves by dragging.
It doesn't happen all the time, but when it does, the only fix is to reboot the machine. Quitting and reopening InDesign does not solve the problem. The problem occurs with both a mouse and a trackpad. The rest of the applications on my computer behave normally during this glitch, so I know it is InDesign-specific. It has happened across several documents, so there isn’t a document-specific issue.
I already installed the downloadable patch released shortly after 2018 came out, and have also completed the recent InDesign update (13.0.1). Neither of those fixed the glitch. I am on a Late 2013 MacBook Pro running 10.11.6 OS X El Capitan.
My work machine is a 2016 MacBook Pro running Sierra, and I don’t recall whether I have encountered the problem on this machine yet, or as often, if so, but if there is a fix without updating the OS, I would like to try that first.
Any suggestions would be appreciated!
