I have tested it in all cursor versions from 0.50.1 to 0.50.7. It is more difficult now to save code in manual mode.
After I told cursor to write some code to a named file, for example, 101_code.py, It only showed code in chat window, but would not save to file. Sometimes I had to open new chat window several times saving a file. Sometimes I selected pasting code to file.
In 0.48, saving file was easy. Maybe from 0.49, it was a problem in saving file.
