First, cron does not provide you with the exact same set of environment
variables that you get when you're in an interactive shell. See the man
pages for 'cron' and 'crontab' for more details. This is not a
Cygwin-specific issue and as such is off-topic for this list.
Second, in Cygwin, cron is run as a service by (typically) the SYSTEM
account. If your program requires interaction with the Windows desktop to
work, you have to enable this setting on the service. It's probably easiest
to do from "Administrative Tools" in the "Control Panel". Go to "Services"
and find the cron service. Double click on it and choose the "Log On"
tab. Check the "Allow service to interact with desktop".
