So I have recently have gotten a new laptop and it seems that the alt buttons do not register with the click to begin making a circle shape on the map. It is as if its a right click on the map so with nothing selected it brings up that small options list of edit, paste, and undo. Computer is a Acer Chromebook 15 running chrome version 67.0.3396.99 , no extensions or add ons relating to this site. I did experience some chrome problems a while back so switched to Firefox, so is this a chrome problem affecting others? Google play store won't let me download Firefox. Thank you for the help
