The InDesign Application Frame gets stuck outside the screen area/behind menu bar
Every so often, since working on my current iMac (2017), my Application Frame in InDesign gets stuck on my second 32" Benq monitor. The top bar area sits just behind the menu bar. Once it's there, it's there. The accessibility to reposition the frame is now not possible. Even switching the Application Bar, the background frame is still stuck and cannot be moved.

Surely, there must be a limit from stopping the Application Frame from running off behind the menu and off the top of the screen, or at least allow an interactive method in a dropdown menu to reset the Application Frame back within the frame of the monitor.
For the moment, the only way I have found to resolve this would be to 'Delete InDesign Preference file' (Shift+Control+Option+Command) on start-up and reapply my personal settings and workspaces.
After resetting, this crucial part of the frame is now visible.

I'm running MacOS Mojave Version 10.14.3, on an iMac 27-inch 4.2Ghz Intel Core i7 running a second 32" Benq screen.
Currently affecting InDesign version 14.0.1 but it also occurred with previous versions too.
