Executor! I cannot move the screen with my mouse, also - I cannot see the green selected grid when I need to circle the units. What’s going on with new update??
A workaround I’ve found is to open Options > Display - Then change the display settings to Windowed or Fullscreen, anything other than your current setting.
When you select the option the window will resize, click “no” and don’t accept the changes. Your grid will now come back and mouse behave like normal
