I agree it could be an touch engine issue. Probably incompatible with the touch screen driver? I messaged the author several times already, no response yet.
I suggest others to try it on touch screen Windows computers. I customized the gestures so that I just use 3 finger swipe down to close apps, 5 finger pinch in instead of tapping the Start button, 5 finger swipe down to hibernate, 3 finger swipe left/right to switch dexktop windows, etc. Basically any keyboard combo shortcut can be assigned to a touch screen gesture. Aside from MS Office, it’s the only paid app I have on my computers
