Loosing nodes when navigating using a pen tablet

Hi, This here is a weird problem. I’m using a pen tablet to work (huion 1060 pro). When I’m using blueprints some times the view port switches to completely another area in the BP graph far away from the area before where I was working. In event graph I can just enter event begin play and it’ll focus back. But when using construction scripts if this happens then there is no way to find the construction script node (the initial one) hence I’m totally lost and have to start again by creating a new blueprint. Is there a way around this? Can any one help me out?
