rebooting makes no change.

no other cygwin1.dll in the path

$ for i in $(echo $PATH | sed -e "s/:/ /g") ; do find $i -name 
cygwin1.dll ; done
/usr/bin/cygwin1.dll

And the only running processes are:

$ ps -e
       PID    PPID    PGID     WINPID   TTY     UID    STIME COMMAND
      4664    5792    4664       4136  pty0    1008 15:10:22 /usr/bin/ps
      3152    5932    3152        184  ?       1960 15:09:43 /usr/sbin/sshd
      5460       1    5460       5460  ?       1008 15:06:52 /usr/bin/mintty
      5792    5460    5792       3792  pty0    1008 15:06:52 /usr/bin/bash
      5932       1    5932       5932  ?       1960 15:09:43 
/usr/bin/cygrunsrv


Another BLODA interference ?
