Hello @arnold_9836,
I appreciate your thorough follow-up, and I apologize for any frustration this may have caused. I have tested this issue on my end with InDesign, Illustrator, and Photoshop running simultaneously, but I was unable to replicate the problem of the document window being obscured by other applications. Since you are using macOS Sonoma, could you please try updating your OS to at least Sequoia and let me know if the problem persists? Additionally, please ensure that there are no desktop management or third-party window-handling utilities operating in the background, as these can disrupt app focus and window arrangement.
Once you have tested this, please provide an update, so I can continue to investigate the matter.
Abhishek
