Have an HP laptop 15-g088ca with touchpad running latest Synaptics driver 220.127.116.11 (8/16/2017). Two-finger scrolling and two-finger right-click both work, but when I do a fast two-finger scroll it finishes by invoking a right-click. E.g., running Chrome, if I do a quick two-finger swipe upward (only touch the pad for a split second), the page scrolls and then the right-click context menu pops up. If I do a slower swipe (touch the pad for a half second), then it scrolls fine (no context menu).
I went thru the settings but couldn't find a fix.
