Indesign 2020, Version 15.0.1, iMac with Mac OS 10.15.1:

We have hundreds of documents created in Indesign 2019 with "chained" anchored textframes, sometimes 4, sometimes 5 frames in a row. Frames are set to automatical height adjust. When text is added to one of the first three frames causing the frame to become higher than before Indesign chrashes completely without warning. Adding text to frame 4 or 5 does NOT create a crash! Same files work perfectly under Indesign 2019. Problem occured with first version of Indesign 2020, and remains after recent update.

Would love to attach an Indesign testfile, but the contact form does not allow ".indd"-files...? I attached a video instead. First I add text to the fourth frame, and everything is fine. Then I add text to the second frame, and when I reach the end of the line (which should cause a linebreak and height-addition to the frame) Indesign crashes completely, without warning, without freezing before, and I am force-returned to the desktop.

I'm using a Mac and running Catalina, have ID 2020. Yesterday, an existing file of 33 pages stopped allowing me to save it. I had no idea it wasn't saving and lost hours worth of work by the time I realized what was happening. I tried starting a new document and pasting the text into it, but same problem. I started a new document again and it allowed me to save immediately, but the second I dropped in text (different text this time), I lost the ability to save the file. I can export to PDF or IDML, but cannot simply save the file.

TO REPRODUCE THE PROBLEM:
1. Import an Excel document that includes straight quotation marks.
2. In the Import Settings dialogue, uncheck "Use Typographers Quotes."
RESULT:
The quotation marks will be converted from straight to curly.

WORKAROUND:
1. Define a paragraph style with "Language" set to "[No Language]."
2. Create a cell style using that paragraph style.
3. Create a table style using that cell style.
4. When importing the Excel content, select that table style (as well as unchecking "Use Typographer's Quotes").
RESULT:
The straight quotation marks will not be converted.

NOTES:
• Changing the paragraph Language to [No Language] does not affect Excel content that has already been imported. Only new imports will be affected (as well as linked tables when they are updated).
• This bug does not affect Word documents. Regardless of paragraph Language, straight quotation marks in Word document imports are kept straight. I haven't tested other file types, but so far, only Excel document and/or table imports are affected.
• Credit for the [No Language] workaround goes to Laubender, who suggested it to me in this Support Community thread: https://community.adobe.com/t5/indesign/bug-deselecting-quot-use-typographer-s-quotes-quot-for-excel-import-not-working/m-p/10841708#messageView2_117be70f9246da

Sometimes when I drag a text box to a different position the screen starts to flicker then goes crazy - like a strobe effect. It's applied to all software that's open and there is no choice but to have a frenzied time trying to shut down applications and saving work before the screen either goes completely blank or white. There is no choice but to restrt the imac.

It happened around 5 times in the space of an hour and then won't happen for weeks.

This user is much unhappy that inDesign 2020 no longer provides the zoom view box that appeared in the top menu bar, directly to the right of the help tab. That was a fast, easy way to change the view size of the file in the screen.

I was told by Adobe that this feature was dropped because the screen size view could be achieved by other existing features. Sure... now one must pull down a tab, then go to another command and activate a feature like zoom in and zoom out. And that only shifts the view in or out by one factor, whereas the zoom view box at the top menu bar would let you instantly jump the view in our out by 3 or 4 "sizes."Count me as a most unhappy user who will stay with inDesign 2109.

By the way... inDesign 2020's menu bar is now empty to the right of "help." So what was gained taking this highly useful feature away? And why not give users the option to have that zoom view menu feature in one of the pre-sets like "Essentials Classics"? I will grumble once more about my unhappiness at the loss of this important feature and the hubris of Adobe engineers to drop such a valuable element of this software.

When fonts aren't activated in an InDesign document, InDesign CC2019 slows down and is practically unusable unless you activate most or all of the fonts used in the document. This wasn't the case in previous versions of InDesign, when you could deactivate fonts intentionally in order to troubleshoot files. In long form documents that may use multiple fonts, this was an especially useful tool.

As InDesign documents are frequently separated from their fonts, especially when using font managers instead of Document fonts, this slowdown becomes a burden when checking files in larger workflows and inhibits font troubleshooting. Could the behavior in previous versions of InDesign, where the activation of fonts was not a requirement for file responsiveness?
