Problem with squared variables

Hi,

I am using Eviews 8. I think there is a bug with eviews 8.

When I estimate Y=c+aW+bZ+cZ^2
and then estimate Y=c+aW+bZ+cZ*Z

I don't get the same results!

Can you explain me the reason please?

Thanks. :D

Could you give a precise example? They should not (and do not) give different results.
