But for my vim7.4.0, ctrl-c can still raise KeyboardInterrupt, then the program stop running. I don't understand what you said that Interrupt signals are already ignored. Because I have not tried Vim 7.4.052. I want to ignore the KeyboardInterrupt, but signal.signal(signal.SIGINT, signal.SIG_IGN) takes no effect, so I tried the code as mentioned to do nothing when ctrl-c is pressed, then the issue occurs. -- -- You received this message from the "vim_use" maillist.
