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
... :-)
