Detailed Description

The Demo Browser is not launching when clicking the edit button if the editor is PyCharm 2026.2.

It was working correctly on older versions. The workaround, for now, is to remove the use of the line number when invoking the editor. It's the line number parameter in particular that seems to be causing the failure.

The Demo Browser in this repo has been updated to remove the line number and the Demo Browser in the psgdemos repo has been updated. It's not been released to PyPI yet.

Cerca nel repository il percorso di avvio dell'Edit-button di Demo Browser e l'invocazione dell'editor che passa un numero di riga. Confronta il codice attuale di Demo Browser con la soluzione alternativa segnalata, quindi verifica su Windows con PyCharm 2026.2 che facendo clic su Edit l'editor si apra correttamente senza che si verifichi l'errore.
