Yes i looked at this post https://answers.unrealengine.com/que…me-window.html, it didnt help. I have the editor closed, i have input game mode in my player class. Still doesnt work on my Packaged test on my desktop. I have 2 monitors, in editor preferences, i do have "“Game gets mouse control” enabled and still nothing works in the packaged state. What is the cause of this? How can i fix it? Also when inside the packaged game, if i hold left click, the mouse stays within the full screen window and my free look works. When i release mouse click, the mouse lock can leave my window and monitor and move onto my 2nd screen
