Resize remote screen is the mode I’m running in, and yes, it appears that when I try to stretch the window larger, then go back to the control panel, that mode is unselected. I see however, that even if I shrink the screen, and then go back to the control panel, the same thing happens. I don’t see any screen with checkboxes. My physical display on the windows machine is quite large, it spans three monitors each 1920×1200 I believe.
