Hi,
if you use LV 7 have a look at the cursors palette under application control (I don't know the exact English names because I'm using the German version; it may be an advanced feature which is not available in all LV versions).
Together with a dynamic event you could implement your desired behaviour maybe (it's a good idea though; the hand pointer is pretty ugly as standard mouse pointer if there's no interactive element).
Cheers,
Carsten
