This worked for me today, thought I would share the
method. I tested this a couple of times (installing/uninstalling).
Pls let me know if anything is incorrect; cron appears to be
running fine. Not sure why I had to create dir /etc/cron.d (it is still
empty - I did so because the application event log had a warning or
error when I didn't).
uname -a says:
CYGWIN_NT-4.0 ARGON 1.3.10(0.51/3/2) 2002-02-25 11:14 i686 unknown
on my system.
regards,
Tom Rodman
