Non-displayed layers blocking queries to other layers

[Rodrigo Del C. Andrade]

    I am not so sure 0 is really the value for OFF (probably is, but 
query result successes return 0 as far as I know, so I always get 
confused), its safer to use the mapscript constants :

	layerObj.setStatus(mapscript.MS_OFF)

    But anyway, you said the top layer is "masking" the underneath 
layer, but what you're really doing is querying? If the layer turned off 
is no longer visible, I suppose your problem lies somewhere else, in the 
query method or the layer being queryed.
