Problem with treeviewer

Dear all, I have a problem with a macro. I would like to stress that as you will see by the following macro I am not a pro-user. The macro is

void macroask()
{

....
}

void macrow()
{

....
}

void macro5_root_bk()
{

    Int_t choice;
    char fn_root[100];

    printf("Are you going to create root files (1) or just to analize (2)?");

    scanf("%d",&choice);
    macroask();
    printf("%d runmax",run_max);
    if (choice==1)
    {

        macrow();
    }
    TChain chain("Eventi");
    for(int s=0;s<=run_max;s++)
    {

        sprintf(fn_root,"Run_%s/run%s.root",namerun[s],namerun[s]);
        printf("Adding file %s\n",fn_root);
        chain.Add(fn_root);

    }
    chain.Print();
    chain.StartViewer();
}

My problem is that if a executed the macro through the

.x macro5_root_bk.C

It opens a treeviewer window but as soon as I try to double click on a leaf I get the error

• Break *** bus error

The same error is NOT obtained if instead of executing the hole macro a pass through command line interface the list of all the instructions contained in the function macro5_root_bk. In that case the double click works perfectly. Any help please?

The second question is connected to the possibility of saving CUTS into treeviewer. I would like to add to the above macro some fixed cuts through the command

item = treeview->ExpressionItem(3);
item->SetExpression("XXXX", "YYYY");

Obviously instead of treeview I should insert the name of the object created by chain.StartViewer() command. Which name is assigned by default to that object?

Thanks
Regards
