Indesign won't save, won't undo

[Silvercat22]

All was fine until today, 12/16/21.  But now, I can't save a file. All I can do is a save as, and overwrite last saved version.  And Undo is unavailable.  I'm working on a deadline and have had to rebuild file, over and over.  This is a crisis, Adobe! 

Running InDesign 16.4 

OS Mojave  on 10.14.6 (18G9323)

Model Name: MacBook Pro

Model Identifier: MacBookPro14,3

Processor Name: Intel Core i7

Processor Speed: 3.1 GHz

Memory: 16 GB

Sys summary attached.

Try restoring your InDesign preferences and caches:

Was able to delete preferences using the technique of holding down Shift+Option+Command+Control.

But ... Now I'm really in trouble.  Now Indesign will not open ANY existing indd files... it will not open a new doc... and it will not open any Adobe template sets. !!? 

[Steve Werner]

Exactly what happens when you try to open any existing file? Error message (if so what is it?) Does the program crash?

[Steve Werner]

Also, have you tried shutting down your computer, wait 10 seconds, then reboot and try again.

[Silvercat22]

There's no error message.  When I try to open an indd file directly from the Finder, InDesign is launched but no document is displayed. 

If I launch InDesign first, and then try to open an indd, the indd is listed at the bottom of the Window menu, but the document is not displayed.

I just discovered a work-around. If I launch an indd directly or via the app,  and  then go to Window-> Arrange -> Float in Window, I can see a tiny representation of the doc in the upper left hand corner and I can enlarge it. (see screenshot)

Yes, I have rebooted several times.

NB - I only deleted preferences...  I did not try to rebuild them; I was under the impression that InDesign would do that automatically. Do you think i need rebuild InDesign preferences at this point? 

[Silvercat22]

P.S. I can save and undo, now.
But the tiny window persists.

Very odd. 

[Peter Spier]

Do you have an external monitor installed? There have been a lot of reports of strange behavior with external monitors.

[Silvercat22]

No. No external monitor.

[Barb Binder]

Yes. Work your way to the bottom of the post @Steve Werner linked to.

Just rebuilt the Cache and Prefs following the instructions at https://www.rockymountaintraining.com/adobe-indesign-rebuilding-preferences-cache/

And then launched InDesign with the fresh new files..

~/Library/Caches/com.adobe.indesign

~/Library/Preferences/Adobe InDesign

Original problem of not being able to save or undo is solved. 

But the rebuild di not help the issues I described in my earlier post today re the tiny window.

And... workspaces not showing and so tools and palettes are not showing.

I know how to go back to previous cache and prefs. 

But this is all very inconvenient and maddening.

Does enabling the application frame help, @Silvercat22?

Window > Application Frame

[Silvercat22]

No it doesn't. 

Just discovered another issue.  Can't get Properties palette to show. Normally I keep it at the top of the window.  But when I try to enable it, it is nowhere to be found.  

This sucks. 

[Silvercat22]

p.s. I can add Properties to side bar, so that's better than nothing. 

A single workspace that I created is half- functional. All others have been lost. 

[Silvercat22]

Control panel won't show. 

[Silvercat22]

OK I tried various combos...  turning on and turning off the application frame PLUS the Control Panel I get the workspace I need.

[Silvercat22]

OOPS - Correction -- with Application Frame turned OFF -- AND--  Control Panel turned ON its all good.
