Hi Wesley (and Jennifer)

Thanks for your response - and you confirmed what I suspected. 

I'll have our software engineer recompile and try your suggestion. I have a question, and not sure exactly what you mean by 

> If (2) is done, you could display the probability fields by putting the field that you want to display into it's own record.


Yep, I tried the netcdf option and that didn't work as you noted. Believe you me, I spent almost all day yesterday trying to get around this issue.

Thank you for your time and effort.
