Unable to move a dialog from one touch monitor to another using touch if displays have separate spaces.
This is a limitation of macOS. It's designed so that any one window is visible on a single monitor, and to move it between monitors the mouse cursor has to move from one monitor to the next. This is of course no problem with a mouse, but not possible with a touch screen!
However, in the system settings / preferences, there is a setting "Displays have separate spaces". With this disabled, windows can span multiple monitors, allowing you to move them between touch-screens. This is only useful if macOS's separate spaces per monitor feature is not required.
A future release of Commander should be able to cater for this and will 'snap' a window to a target monitor when the touch reaches the edge whilst moving a window.
