Grads on Rocks from a Mac OS X PC

[Andrea Cimatoribus]

Hi, I'm having troubles using grads from my mac (OS X 10.4) on a
cluster machine running Rocks (v. 4.0.0).
Grads starts up normally, but after typing return on '>Landscape
mode?' I get Segmentation fault.
Any idea?
Other people use grads from PC with no problem, but at least another
user has the same problem using grads from a Mac OS X 10.3  on the
same machine.
Grads works using a script to print a file with 'printim'.
Thanks,
Andrea
