[ID-4271100]With Application Frame "OFF", Green Maximize Button Doesn't Zoom to Fit Anymore
ID 21.0
OSX 15.7.1
Just updated ID and all the previous docs I've been working on today, are opening in huge windows. It takes a few resizes to scale down the window, then grabbing the bottom right corner to resize the window finally, it's jumping away from the cursor.
Resizing windows when tiling still does that (as per the previous version/bug), which is also super annoying. Please fix all these bugs!! It's like no one at Adobe uses these products

    Hi,
Thank you for reporting the issue. We have been able to reproduce the issue, and it is currently under investigation.
In the interim, you may continue your work using by turning "Application Frame" ON

 commentedVersion: InDesign 21.0, MacOS 15.6.1 Steps: Opening any document or making new document. Application Frame off. Expected: Document window should expand to the edge of docked pallets but not go underneath them (behavior prior to v21.0) Actual: Document window always expands to the screen edge underneath any/all open pallets.

 commentedYes application frame doesn't have the issue but I've never been a fan of it. Beta is fine, just the new 2026 version

      Anonymous commented Just updated to InDesign 2026, and document windows are running behind tool windows (e.g., Swatches, Paragraph, etc.), all the way to the right edge of the screen. In the past, dragging those tool windows all the way to the right edge until I get a blue bar, fixes this issue. Now it does not. And the application does not remember the size I resized the document window to on last save, and it opens it all the way behind the tool windows again. This is super frustrating, as I am often referencing something outside of InDesign on my screen ... and I have to limit the height of my tool windows so I can grab the bottom-right corner of the document window and resize it ... EVERY TIME I OPEN THE DOCUMENT. Please fix this ASAP! Thank you.

 commentedIn InDesign 2026, the green maximize button in macOS changed from Zoom to Full Screen (new, separate Desktop) when working with the Application Frame turned off. In InDesign 2025, it was great to click the maximize button and the window automatically resizes to fit between the tools and panels. In 2026 it opens in a whole new, separate desktop. Holding Option and clicking doesn't work. Again, I am using InDesign with the Application Frame disabled.

      Jean-Claude Tremblay commented This happens when you have Application Frame disable. Definatly a bug in 2026.

 commentedHi. In ID 2025, I could open a document when I already had a document open, and the new document window would fit the existing window. In 2026, the new document forces the window to expand to fill the screen. This is a problem because I often have a PDF and InDesign file open side by side to do corrections. Now, every time I open a new InDesign file to make edits, it fills the screen over my PDF, and I have to resize the window over and over. It's not a huge ordeal, but it is an inconvenience that has popped up in 2026. It'd be great if it can be returned to the behavior in 2025. Thanks!

 commentedRather than the Maximise button on Mac fitting the document window to the available screen around toolbars and panels, in InDesign 2026 (21.0) it goes to Full Screen Mode and doesn’t not allow you to escape out of it hiding all panels and toolbars. Only a Force Quite resolves the issue.
