InDesign opens in the middle of my two side-by-side monitors

[June Rabbit]

I have two identical monitors, side by side. I always use InDesign in the left monitor, but every time I open it, the window straddles both monitors with half of the windo in the left monitor and the other half in the right monitor. I always move it over to one monitor, but when i close it out and open InDesign again, the same thing happens. This is annoying and I'd like to find out why it happens and what I can do to get the program to open on just one monitor instead of straddling both.

What version and platform? Mine used to do that but not recently.

[June Rabbit]

I am on Windows 10 Pro.
Right now Creative Cloud Desktop says I have InDesign version 18.1.
I always try to have my Adobe programs updated to the most recent version.

Have your reset your preferences. That seem to fix so many issues.

• Windows: Start InDesign, and then press Shift+Ctrl+Alt. Click Yes when asked if you want to delete preference files.

• macOS: While pressing Shift+Option+Command+Control, start InDesign. Click Yes when asked if you want to delete preference files.

Thanks, I'll keep this in mind. I had to press Ctrl+Alt+Shift at the exact same time to get the popup window, but after selcting Yes to deleting preference files after selecting "Yes" to delete preference files, InDesign took a moment and then opened on just one monitor—clean and simple. If the problem comes up again I'll update this reply.

Make sure to save your screen layouts as Workspaces, I find them so useful (main display on left with all panels on right screen, one as opposite, one with no panels...)
