I’ve cleared preferences through library, and when starting indesign.

It has several bugs randomly appearing.

eg. Suddenly can’t undo, takes ages to quit, there’s a slight delay importing images...

Hi @Mrinalini26,

Sorry to hear that you’re also experiencing this issue and sorry for the delay.

Could you please go through the discussion shared below and confirm whether the behavior you’re seeing matches what’s described there?

As a workaround, please try disabling all Generative AI-related options/checkboxes from InDesign Preferences and then test the workflow again to see if it improves the behavior.

Additionally, it would really help if you could share the requested details mentioned in this thread:

Those details will help us investigate this further with the product team.

Looking forward to your update.

I’m having the same issues with this updated 2026 version:

Can’t undo
Sometimes switching tools doesn’t reflect on cursor
Slow performance

I’ve been having the same issue with 21.2 and now installed the updated 21.3 Indesign and I still have the same issue:
– Undo stops working completely and cursor changes to a different tool and Quit doesn't work.
– I then have to force quit and then re-open Indesign.

I am running on a Mac Studio with OS 15.7.3 (24G419)

If I ditch the prefs this doesn’t make a difference.

Any ideas?

Hi everyone,

Thank you for continuing to share your observations and details around this issue, and sorry to hear you’re experiencing this.

I wanted to let you know that I’ve logged a bug for this behavior with the product team, and they are currently investigating it further.

For reference, this also appears related to a similar discussion here:
https://community.adobe.com/questions-671/indesign-21-2-undo-greyed-out-and-history-panel-blank-on-macos-tahoe-and-ventura-1551926?postid=7514324#post7514324

To assist with the investigation, it would be really helpful if you could share a short screen recording demonstrating the issue in action (undo not working, slow quit, import lag, etc.). This will help the team better understand the behavior and narrow down the root cause.

The team is actively working on identifying the cause and a possible fix. I’ll keep this thread updated as soon as I have more information.

Thank you for your patience while we look into this.

Well I have the latest OS, the latest InDesign version, aparently Adobe is now adding alt-text in documents without my approval, and undo doesn’t work!

What’s your operating system version? Also, you can disable alt text in Preferences > Generative AI.

Hi @Rob29557400wpqk,

I’m sorry to hear that InDesign has been behaving like this. In line with the expert’s suggestion, could you please share your full system details, including the exact OS version you’re using?

Also, could you please describe the undo issue in a bit more detail? For example, does it stop working completely, skip steps, or show any error? If possible, a short screen recording demonstrating all the three issues would be really helpful so I can review this more closely.

Looking forward to your update.

It seems OK now, perhaps it was Indesign version control my end. I’ll get back to you if I encounter more issues.

Full system specs, please. The undo bugs were supposed to have been fixed with 21.2.
