Ah, you were right! Actually there were no *real* processes remained (Otherwise I could not have overwritten cygwin1.dll, I think), but I remembered that there is a remaining *fake entry* in the result of `ps' as follows (for which `kill' produces error `No such process' and also I cannot find any corresponding process in Windows Task Manager). $ ps uaxf PID PPID PGID WINPID TTY UID STIME COMMAND 1416 1 1416 11160 ? 197610 Jan 20 /home/murase/opt/screen/4.7.0m/bin/screen-4.7.0 After a reboot of Windows, the problem has resolved! Thank you! Koichi
