Can anyone tell if there still a hot key to interrupt executing command (like Ctrl + C prior to 3.20 version ) Thank you in advance.

Ctrl+C is not specific to star-cd, it is system dependent,

Ctrl+C should interrupt all executable on your machine not only star-cd...

I think Guang Ai meant ctrl-c in the pro-star command window rather than in a terminal window. So he's asking about the functionality provided by pro-star to interrupt a command, rather than the functionality provided by the operating system to kill an application. Anyway, as far as I know, it should still work.

Thank you all. However, for window version 3.22 on my machine, Ctrl+C does not work, failed to stop vertex being accidentally plot to screen. I could do it before 3.22.

Have you reported it as a bug?

this is specific to windows, your key sequence 'Ctrl+C' might not be associated to a program interuption on your windows machine. You will have to do without and be caroful.

I came accross different problem over time, and all caused by user side not a real bug. This time it is really annoying.

Report it is a bug. That sounds to be what the problem is, and this is porbably the only way to get it fixed.
