You have, of course, reviewed

and thought of attaching the output of "cygcheck -svr", right?  Also, did 
you try "cron_diagnose.sh" (Google for it)?

I suspect some or all of your mounts may not be visible to cron...  Do 
your cron jobs above (i.e., 

19 17 * * * ls >> /tmp/debug.log 2>&1
20 17 * * * ls -l /tmp/myscript >> /tmp/debug.log 2>&1

) still work correctly after changing "ls" to "/bin/ls"?  Does changing 
"/tmp/myscript" to "sh -c '/tmp/myscript'" help any?
