Try adding something like
export DISPLAY=localhost:0
or
setenv DISPLAY localhost:0
depending on which shell you use and where your X server is, to the
script run by cron.
Connecting to the X server is done automatically to ensure that
system/view/screen-face/size is set correctly. That's why you see
the error.
View/Pro is not really intended for use with non-interactive scripts.
That's what Command is for.

No. Sounds like your user.r is wrong. You are probably using different
settings (for proxy or ftp-passive) for Command than you are using for
View/Pro. If you installed Command and View in different places then
your user.r might just be in the wrong directory.

Asking on the mailing list is usually the easiest way. We do respond
through feedback as well, and sometimes more quickly, but have fallen
a little behind there recently, partly due to vacations. Sorry for that.
