[ferret_users] small numbers cause ferret error

[Hella Riede <hella.riede@xxxxxxx>]

Dear ferreters,

I encountered problems using my ferret scripts after moving from version 
6.40 to 6.64. The very small numbers that appear in some of our model 
output (which is my ferret script input) cause an error in ferret. To 
avoid the problem, they could be set to zero defining a certain 
threshold. However, I preferred the previous handling without having to 
use any manual thresholds - what happened? Has this been fixed since 
version 6.64?

Kind regards,
Hella
