When you long-press right-click on the mouse and then move the mouse, you may have issues with the game or even close the browser tab.
But it's easy to fix! Simply check browser settings. Go to Advanced settings. Check "Mouse gestures" 一 they should be off.
Mouse gestures are enabled by default on Windows and could be enabled on other operating systems.
