On Mathematica 12.0 for Windows, I have a package
foo.wl, and a testing notebook
fooTests.nb. My first test loads the file:
Get[NotebookDirectory <> "foo.wl"]
I had left code in
foo.wl that causes an infinite loop; realizing this I first tried Alt + . but had to quit the kernel through the menu. Immediately after this, I was unable to edit or select anything in the testing notebook. When I saved and quit
fooTests.nb, then relaunched Mathematica, the problem persisted. I can't copy and paste the tests to a new notebook.
- Can anyone reproduce?
- What's the cause?
- Can I get my testing notebook back?
