Hi,

Not this isn't the correct behavior.

There is a bug in the selection function. A break statement is missing.
This is will be corrected in next patch for gtktree.

But you can correct this easily.
Edit gtktree.c.
In the function gtk_real_tree_select_child, add a break statement at
the end of the case GTK_SELECTION_SINGLE, just before case GTK_SELECTION_BROWSE

      gtk_signal_emit (GTK_OBJECT (tree->root_tree), 
		       tree_signals[SELECTION_CHANGED]);
>>      break;


    case GTK_SELECTION_BROWSE:
      selection = root_selection;
