Sometimes when I remove markers they stay around in a "ghost" fashion -- they are clickable but there's no more icon. This is not every time and usually only happens when I remove more than one at a time. Here's my code for removing markers: for(var i in markers) { google.maps.event.clearListeners(markers[i], "click"); markers[i].setMap(null); markers[i] = null; delete markers[i]; } The only way to guarantee that they get removed 100% of the time is to move the map to another position. Then when I move it back they are gone 100% of the time. Thanks for your help.
