I have TeXmacs and Octave installed, both working properly otherwise. I have also added the path to octave executable (i.e. C:\Octave\Octave-5.1.0.0\mingw64\bin ) to the Windows environment variables and octave runs in cmd/PowerShell terminals and Jupyter with no hassle. However, when running Octave inside TeXmacs through Toolbar > insert > session > octave it gets stuck on Busy... , the same reaction for any other commands as well:

Octave gets stuk on Busy... inside TeXmacs.

This is my environment:

TeXmacs 1.99.9

Octave 5.1.0 (installed through Chocolatey)

Windows 10 version 1809

I would appreciate if you could help me know what is the problem and how I can solve it.

P.S. I have reported this issue in the TeXmacs repo.
