<div dir="ltr">If you are using PNG images this is a known issue and there is little you can do beyond trying another format such as GIF or telling your users to get a more modern web browser. There is a hack to enable the use of alpha transparency int he PNG images within IE6 but it has a severe effect on performance.<br clear="all">

<div dir="ltr"><span>hi.<br>I use more than one openlayers vector layer to overlay the map. every layer has its event. in IE6, the upper layer covers completely the lower layer. so, the other vector layer event can not be triggered. in IE7 or firefox, there's no this issue.<br>
I try to render the vector layer div border, and find the div fill the entire map. in IE7 or firefox, the border shrinks to the <span>top left corner. so the layer don't cover the lower layer.<br>
</span><span>how to solve this problem ? </span>thanks. :-)</span><br></div>
