querying polygonal layers from KML in Google Earth

[pere roca ristol]

 I have different polygonal layers in google earth, on the same folder. 

 One layer should not be queryable, the other one yes. If the non queryable layer is visualized, I cannot query the queryable one (which is over the other one, covering the same area). I have tried to put each layer in different positions on the folder without success. 

 I am starting to think that I should convert the non-queryable polygon to lines. Should it be the only solution? there is no tag in KML to say this is queryable layer or not? 

 And what if I want to overlay two queryable polygonal layers and query them separetely? 

 thanks in advance,
