gtk_clist_moveto problem

[pasp <pasp ll pl>]

Hello list!

I've created clist widget placed within a ScrolledWindow widget and filled with 64 items.. it's look nice, 
but...

Why the following code:

    [...]
    gtk_clist_freeze (GTK_CLIST(clistbox));
    gtk_clist_moveto(GTK_CLIST(clistbox), 28, -1, 0.0, 0.0);
    gtk_clist_select_row(GTK_CLIST(clistbox), 28, -1);
    gtk_clist_thaw (GTK_CLIST(clistbox));
    [...]

doesn't move 28th item on top clist ?


regards,
        tomek
