Thanks for trying. These are indeed puzzling, and I don’t remember hearing of these issues before (ctrl-v not working in the editor, not seeing the right-click menu, not seeing text content when opening a file). They seem pretty egregious and noticeable, so I’d be very surprised if they were widespread.
Sometimes people have posted about very odd behavior happening in older browsers, or browsers with extensions that changed the page structure. It’d be a great help if you could post:
- The browser and browser versions you are using
- What JupyterLab extensions you may have installed:
jupyter labextension list
- Do you see any errors in the server console (where you launched JupyterLab)
Edit: I see above you said you tried both Firefox and Chrome on Ubuntu 18.04 for the right-click. I assume the latest versions of those browsers?
Edit 2: And I understand if you don’t have time to try to debug this further. It’s just really puzzling to me the symptoms you are seeing, so whatever debugging information you can post will help narrow down if the problems are with your installation or with JLab itself.
