So I've created a GUI that allows you to sync data to a video and mark specific points on the data that correspond to moments on the video. I'm having an issue with ginput() that is fairly odd. When I left click, it rolls back the video (expected). When I right click, the video goes foreword (expected). If I add in an

elseif button == 0 
disp('works correctly')

it does whatever it's supposed to when a left-double-click occurs. But when I try to go foreword multiple times very quickly by right clicking (double-click speed) it rolls the video backward.

As far as I know there is no right-double-click option for ginput, but it seems like that's what's happening.

[~,y,button] = ginput(1);
if isempty(button)
      return
end
while button ~= 2
    change = (y - yLim(1))/(yLim(2) - yLim(1));
    if button == 1
        PlayerWindow.controls.currentPosition = PlayerWindow.controls.currentPosition - change;
      elseif button == 3
          PlayerWindow.controls.currentPosition = PlayerWindow.controls.currentPosition + change;
      elseif isempty(button)
          return
      end
      [~,y,button] = ginput(1);
      % get next input
  end
end
