Version: InDesign 15.0.1 x64
Issue(s): 1. One example is that when working in InDesign and go to save a file the application shows that the icon is spinning and never seems to stop spinning. Then an error message pops up on the screen indicating some sort of issue and then the application crashes to the desktop.
2. When opening up a file that I have been working on it takes a while to open and when it does open it opens a prior file that I was working on.
Expected Results: 1. When saving a file I am expecting the application to save as normal and to bring me back to the application and not crash.
2. To open the file that I requested to be opened.
Actual Result: 1. File does not save as expected, errors out and then the application crashes.
2. File requested to be opened opens, but opens with another file as well.
Example: See attached Windows Event log for application crash details for issue #1.

After updated to 2020 version that added support to Asian languages (include Thai), it look like Indesign force user (in my case Thai) to set language in Advanced Character Formats to Thai. After set the language Indesign also require me to use World-Ready Composer to set all tone marks in place.
.
Before the latest version, I always avoid to use World-Ready Composer because it combines a word to single object, not just locks tone mark and float vowel to character in the right position. By which it impossible to navigate with text tool to the position of text that I want to revise, even if I use right/left key to navigate. It mostly skips word by word, not only character by character. And when I delete a word or a character, some time it not only deletes backward but forward too. (I think because of when I delete character form a word Indesign instantly recognises new word and forces to delete that new word.) But After updated to 2020, I think, I anymore cannot avoid World-Ready Composer.
.
After I designed to use World-Ready Composer, I found one more bug. Because in many situations when I craft the spacing in layout (especially in Thai), I always use thin-space to separate character like “ๆ” form word before and after to make the space between them look good. But After I set to World-Ready I found that when thin-space (include other spacial white space like en or em) is in the back of the line the spaces in question act like normal character, so the last character of the line when use left justify do not snap to right frame border. The space still there like It becames one of character. So you can see the gap between the last character and the right frame border. (you can find this instance in attachment in file “space issue.”)
.
But the serious issue still there after the update. I, and all of my co-workers, found that everything about word wrapping in Thai language goes wrong after updated to 2020 version. This never happen in the former versions. I don't understand why this issue is happen. Even if I use Discretionary Line Break to help Indesign to wrap text properly. But It is not productive at all, because I had been forced to read text all over again and to insert Discretionary Line Break to every lines. (you can find this instance in attachment in file “wrap gone wrong.” In the high-light is the words that should be stick together.)
.
PS. while I wrote this issue report, my co-worker tried to migrate back form 2020 to 2019 and she found that when copy revised text back to 2019 it not the same character encoding. I advised her to try to place that text to TextEdit. It appears that some character is changed to something that is not unicode at all. That never happen in previous versions too. ((you can find this instance in attachment in file “text form 2020” and “text form 2020.” the text form 2020 at frist did in 2019 before migrate to 2020.)

Working on a catalogue, a lot of files in a book. The "fit frame to content" works good until after a lot of pages (I think after 50 or 60 pages) suddenly it doesn't work anymore. With a textframe & also tableframe. But with an image it still works...
Also very change, when you split the textframe in for example 2, on the second textframe it will work (fit frame to content).
All the fit options don't work for text & tableframes.
The right-click and choose the option don't work and also the shortcut doesn't work.

2 other colleagues have the problem too (same version).

We use this option a lot, because we imported an XML and then we need to adjust the textframe after placing it on the page.

Hope this problem will be fixed soon, haven't seen anyone reporting this issue. Thank you!

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.
