Mouse kicks me out of the game
Does the game close or minimalize? If it minimalizes press alt-tab to cycle through open screens, and reopen the game. If the game actually shuts down your problem is bigger than I think anyone can solve, in that case, uninstall the game, reset all graphical and control drivers, and reinstall the game.
It’s a Windows 10 Update issue.
Right click GW2.exe, Properties, Compatibility → Windows 8
I spent too much time figuring this out for myself. Hope this helps.
WOW that worked Thanks AshG.1039
