EMClient always opens new mail window off the desktop screen

I have two monitors, side by side each with 2160x3840 display resolution.

Whenever I try to create new email, emClient opens the new email with partially off the screen to the right and above the top of the right monitor. I have discovered the Win-RightArrow key to allow me to move it back to the desk top… but the next email has the same problem.

Why doesn’t EMClient remember where to open new mail windows and why does it open them off the screen?

Appreciate any and all ideas.
