@Michael-Vincent Data conciergery is a computer’s job

Hi @franz-joli , I haven’t come across such behavior myself and cancelling compare on my side has always been working flawlessly. As @peterjones had already kindly suggested, If you continue to experience such problem you could open an issue here and describe it step-by-step starting with your Notepad++ setup and plugin version (by providing the Notepad++ Debug Info... from its ? menu) and it would be great also if you could provide example files to try on my side. We can discuss the problem further there. Thank you Peter, precise and helpful as always! :)
