drawQuery() help

Hi,

I have coded an application (using MapScript) such that when I perform a
query-by-point it iterates through all the query-able and displayed
layers in the order of last drawn to first drawn to look for a result.
Once a layer yields results I stop iterating over the layers as I only
want to see the result from the layer that is visible at that point.
(Hence I am iterating thought the layers in the reverse way to how they
are drawn.)

Anyway, the image that is drawn doesn't highlight that single layer that
yielded the results, instead it highlights the bottom visible layer
(i.e. the first drawn + visible layer). Obviously I want it to highlight
the layer corresponding to the results found.

I'm really not sure where to go on this hence I'm asking for any ideas
to help me out.

Cheers,
Nelson
