Marco I thought mc's lacking subshell support is a hard fact of life in Cygwin, until the -U option was pointed out here. It's a huge improvement. It's quite easy to kill the zombie subshells. Put a line into /etc/crontab (assuming you're running cron): */6 * * * * SYSTEM ps -a | sed -n 's/I *\([0-9][0-9]*\) *1 *..*bash$/\1/p' | xargs kill -KILL This will kill all bash processes every 6 minutes, who are waiting for input in the background (I) and whose parent process (PPID) is 1 (not a terminal, not mc).

Best regards Gergely That is a workaround, it will be better if Pavel release a mc cygwin package without this problem... mc-4.6.1 is 22 months old and eventually 4.7.0.x works better.

Bash does of course forward the SIGHUP it gets from the terminal to its child processes, and manually sending SIGHUP to the orphaned mc does get rid of it. A similar issue was previously reported against the joe and mined editors at http://cygwin.com/ml/cygwin/2010-04/msg01013.html. This still needs a simple test case though.
