I have looked for threads about this and haven't seen any, so here goes.
I am running InDesign 13.1 on a MacPro running OS 10.13.3.
I have three Dell monitors, the right one is vertical and it has the OS Menu bar and some [long] InDesign palettes.
The center is horizontal and holds the Application Frame, the left monitor is horizontal and holds a number of InDesign palettes.
I want the Application Frame to open on my center monitor at launch -- it opens on my right-most monitor so I have to move it every morning.
I know it CAN work because it works for Photoshop [19.1.2] and Illustrator [22.1] plus it DID work with InDesign 2017 [12.1.0].
I have saved a custom workspace many times to no avail.
It worked with InDesign 2017, so is it an InDesign 2018 thing?
I thought the Application Frame always sat wherever the main (OS) window bar was. But you said it worked with 2017...maybe try making the center monitor the one with the menu bar...
Ideally InDesign and other Adobe applications too, should open on the monitor where it was closed last time.
If it is not opening on desired monitor , please try setting the second monitor as your primary screen and check how it works?
This certainly doesn’t work on Windows. InDesign on a multi monitor system on Windows is absolute travesty unless both monitors are identical and set to identical scaling percentages.
Shortly after I posted this question it worked, and I 'm thinking it was likely due to doing [absentmindedly] what you have outlined here.
GREAT SCOTT! I found the answer!!!! It took me a while to figure out. It bugged me for so long. GO TO
WINDOW >> APPLICATION FRAME
When "unchecked" it keeps it locked on the one monitor. When Checked, you can move the application frame to another monitor.
I think this depends on what you mean by 'application frame'. The window itself, with the document you are working on, can be moved freely around. But, at least for me, that 'application frame' is either stuck on the wrong monitor, or it is not there at all (unchecked for 'application frame'). So for me, it is a 'fix', but not at good one at all ...
Same! Project window moves freely to second monitor, but application tool bars etc. remain welded to first. Maddening!!!!
I've been havig the same problem: project window moves freely to second monitor, but application tool bars etc. remain welded to first. Clicking Apllication Frame on worked for me. It freed up the tool bars and frame so that the whole thing moves to the other screen together. THANK YOU!
I had same issue with project window moves freely to second monitor, but application tool bars etc. remain welded to first. I tried the solution of clicking aplication frame, but it doesn't worked to me. I am using MacOS Monterey Version 12.5.1, M1 Pro chip.
Have you resolved the issue yet? I find myself having the same issue.
I updated, then deinstalled the app, when reinstalled and restarted the problem was resolved. Seems dumb, but it might have been a bug they fixed in update.
Same exact issue here, same system set up. Clicking Application Frame does not work. I'm constantly trying to fix my InDesign workspace every day, and it doesn't help that I switch to different types of second monitors when I'm working from home vs. going into the office and using theirs.
