Hello, I have a problem with the "layer tool" window, while I am editing my PCB: When the mouse is not on it, there are 4 layers. When I move the mouse on it, the window is bigger and 8 layers are visible. But when I want to clic on "view" or "edit" of the 2 first (copper layer and component layer), the layer window reduced and my clic is not validated. So, I am not able to edit my board :(  edit : the problem disapeared after some refresh of the page.
