[Octave-bug-tracker] [bug #42603] GUI: allow only one instance

[Armin Müller]

Follow-up Comment #2, bug #42603 (project octave):

Association: This is done by the Windows installer. Option "Register .m file
type with Octave". See screenshot attached.

Opening: Well, at least using Windows, clicking a *.m file will open it in the
Octave editor (not: run. This would take some more care because *.m files are
ambiguous between script / function). This is also what Matlab does. In
addition, clicking a *.mat file will load data into the Matlab workspace.

FYI, here is an explanation of the file name extensions and what they are
suppoosed to do:

Reuse an existing instance or start a new one: Matlab would reuse the existing
instance. It is commonly reported as an error if a new instance is opening,
here an example for Windows 7:

Two instances: I did not test it lately, but imho the most recently used
instance will catch the event.
