thanks ngerber.
but you may misunderstand my issue.
It doesn't relate to PNG image.
I use some OpenLayers.Layer.Vector as map layers. these layer will
display LineString, Polygon etc. and each Vector Layer has its
JavaScript event. But, in IE6, the top vector layer covers the map
completely. It will result in the lower vector layer's event can not
be responsed.
In IE7 or FireFox, it works well. Every vector layer's event can be triggered.
