Also, as a workaround you can try to work in Typical display Mode.
Set the Typical mode by navigating to View-->Display Performance--> Typical Display. It should resolve your issue.
Thanks in Advance
I sent you an email already with the video. On the video https://www.youtube.com/watch?v=U_5oerQyczE it is stuck at the beginning and almost at the end.
The weird thing is; when the freezing is happening - the Mac spinning wheel is not showing, but on my computer it is.
With the same problem with InDesign CC 2017 since one week, I turned off my wifi ... and I could finally work.
But it is not a definitive solution, I hope that Adobe will be able to fix this bug ...
I wonder if your application has fallen prey to the "must continually check hyperlinks" behavior of InDesign. Not sure if you are using hyperlinks, but you might try unchecking Auto Update URL Status in the Hyperlinks panel. Normally, this wouldn't be the first thing I'd reach for, but saying that it gets fixed when disconnecting from the internet made me wonder.
I have the same problem. I have noticed my indesign freezes every time my internet slows down, specially when I am uploading something into dropbox for example, it has a HUGE affect on Indesign.
Is there a way to disconnect Indesign from the internet instead of having to work offline?
Are you storing your files on a server rather than your local drive?
InDesign doesn't work online, you download the application to your computer and use it in the normal way. Adobe checks (possibly once a month) that you're up-to-date with your subscription. So the internet will have nothing to do with your application slowing down.
