I am trying to modify a PCB without modifying the schematic. I want to replace a component, so I would like to place the new components directly on the PCB, connect them temporarily with ratlines, delete the old component, and move around the new ones to find a good placement. When I select the "connect pad to pad" tool from the PCB tools the red cross hairs appear but I am not able to make any connections. When I press "escape" the cross hairs disappear but appear again as soon as I move the mouse. To remove the cross hair I have to select another tool and then press escape. I have tried with top, bottom, multilayer, and ratlines layers active with identical results. What am I doing wrong?
