Dear FLUKA users

a respin, Fluka2008.3.7, has been just pushed to the web sites.

It contains corrections for a couple of rare PEANUT crashes, as
well as a (partial) protection for inputs which redefine a standard
material with a very different density, without defining or
undefining through MAT-PROP the relevant gas pressure.

E.g., if the input is redefining Helium, which is predefined at its 1 atm
density/pressure, and the density is changed to the one of liquid helium,
of course the input should also undefine the default gas pressure (1 atm).

If this is not done (and apparently many users forgot about) crazy dE/dx
results can occur. Now a (partial) protection is built in the code.
It would be anyway better to define (or undefine) with care the pressure
when required.

As usual, assistance and bug correction will be done only on the latest

               for the FLUKA developers
