At my company network I was editing and debugging an .m-file residing on a network share. The subdir where that .m file lives is in the path, but that mentions a UNC path rather than a drive letter.

When I wanted to add a breakpoint I got popups like the one shown in the attached pic.
My conclusion is that the file editor (or is it 'file_in_load_path' or other internal Octave functions behind the scenes?) doesn't recognize that the drive letter path and the UNC path point to the very same file.

Quite intriguing is that I already had a few breakpoints in the file (I can only have put them in by double-clicking in the left margin before running the .m-file) and had execution stop at those breakpoints as well. So the popup comes "as a surprise", right out of the blue.
I don't remember if I had saved the file in between runs before I got the popup, but that may play a role.

Here I'll just mention the old bug reports bug #62847 and bug #62865 about similar issues relating to drive letter / UNC paths and the search path. It looks like the UNC vs drive letter saga in Windows networks keeps lingering on ... :-)
