NCL and stdout

I have a curious bash issue that I need help with.

When I execute

ncl program.ncl > program.out &
tail -f program.out

I receive no output. The program continues to run in the background, but
the file "program.out" remains empty. When I run

ncl program.ncl

I immediately receive output. Why is the redirect not working in this case?

Is this something unique to NCL or is this a problem with the way I have my
shell profile setup?

Just curious,
