The left and right gestures(go back or forward in web pages) sometimes doesn't work properly and i get a context menu instead.
To reproduce,do a gesture in xyplorer forums and you will find it.Link -- https://www.xyplorer.com/xyfc/viewforum.php?f=2
I'm using windows 10 and latest version of FK.
Gestures not working properly
Tried it and it works for me. Probably you are holding the mouse button too long. You can set the settings in Preferences/Gestures.
Try increasing the Initial timeout.
