Problem 791

I have the same problem as described in bug #745:

my system is SuSe Linux with gcc 3.3.3:

ychen@droplet:~> gcc -v
Reading specs from /usr/lib64/gcc-lib/x86_64-suse-linux/3.3.3/specs
Configured with: ../configure --enable-threads=posix --prefix=/usr
--with-local-prefix=/usr/local --infodir=/usr/share/info --mandir=/usr/share/man
--enable-languages=c,c++,f77,objc,java,ada --disable-checking
--libdir=/usr/lib64 --enable-libgcj --with-gxx-include-dir=/usr/include/g++
--with-slibdir=/lib64 --with-system-zlib --enable-shared --enable-__cxa_atexit
x86_64-suse-linux
Thread model: posix
gcc version 3.3.3 (SuSE Linux)

This system runs ok with Geant4 5.2. but recently when I upgrade it to
Geant4 7.0.p01, there was no error or warning with compilinh and link with
examples and the problem occured when running e.g. N01:

In bug#745, there is a link for solution, but I cannot see that page as I go
to Geant User Forum:

The connetion was refused when attempting to contact
geant4-hn.slac.stanford.edu:5090


Can someone email me that solution or put it on an easy-accessable webpage?

Thanks,
