In Notepad++ 4.8x you have the option to add a blank file (asNotepad.xml) which amongst many things enables several instances (-multiInst)
If this parameter is set, you can accidentally open up the same file in another instance thus leading potentially to conflicts.
IMHO Notepad++ should
A) Check if the file is already being edited (in Notepad++) and bring that instance (the one editing the file) to focus B) Continue load the file in an new instance and warn the file is already being edited in another instance.
