Segmentation Fault

[ROMAN ANTONI KAMINSKI]

I'm am beginner as GRASS user ans as workstation user.
I use SPARCstation20, Solaris 2.4, xgrass4.1, binary Sun version.
Very oft I get the message: Segmentation Fault - core dumped.
First question: how to use this core file? I can't read it.
Last faillure was by displaying the title of a map.
Another question how to change handy the display monitor from x0 to 
x1? Which one is active one?
