Hi Folks,

The actual fault lies in 'cj-defrag' where 'cjx' mails the output 
of 'cj-defrag'. 'cj-defrag' calls a child script 'sd-defrag' and 
all 'sd-defrag' does is call "df.exe". The single line at the bottom 
simplifies the problem: do a quick defrag of the E: drive.

The other issue was $TMP being set to somewhere unwritable. This is a work 
machine so I'm assuming it's some daft policy setting. Setting TMP 
to "/tmp" fixed that.

$ crontab -l

User "cyg_server"  is a member of "Administrators" and UAC is disabled. I 
have checked the "Run this program as an administrator" option(*) on the 
shortcut (compatibility tab) to the desktop mintty terminal before 
running 'cron-config'.

(*) Ditto for "setup.exe". Created a shortcut to that and always run as 
administrator.

When I run..
"/cygdrive/c/Program\ Files/Defraggler/df.exe E: /QD"
..from the mintty command line all is well.

It appears (**) the cron daemon is not getting privileges to run "df.exe" 
but I am stumped on how to proceed.

TIA
Guy
