Hello,I have noticed that there are couple of archived forums asking this question. I recently had to figure out how to change the z order on the infowindow myself, so I thought I would share my solution with you.The only way I could figure out to do it was to modify the z index on the 'map_infowindow' html element. See the code below:
dojo.connect(map.infoWindow, 'onShow', function(){
document.getElementById('map_infowindow').style.zIndex = 9999;
});
This code will make sure that the infowindow is always on top. I hope this helps,Mark
Regards,
Mark
