In the past I used to use the toolbar button to “Open in board editor” and the “Open in Schematic Editor” to open the Board/Schematic editor but also to go to the editor if it is already open…
Right now in this version, it does not behave the same way anymore.
If the Board/Schematic editor is already open, then KiCad throws me the annoying “File opening warning” popup saying the Schematic/Layout is already open. If I say, “Open it anyway”, it will launch a new instance of the tool instead of focusing on the already opened one.
Another annoying thing is that if I click “cancel” to not open another instance of the Editor with the current schematics/layout it will not open it but it will leave an empty instance of the editor there.
No. I am running a complete project, I also launched it with the main Kicad project window.
Something different I did this time was to use the “curved tracks” plugin which generated a new kicad_pcb file inside the same project (but with a different name). However, I am not editing that file. I am going to remove it to check if changes something.
