Hello Esteban,
Most likely after the popup closes there is a javascript error in your
page and navigation breaks (zooming in/out shouldn't work at this
point). Use firebug to see if you get an error in the console.

Hi,
I'm sorry, but I have a problem.
When I implement this, I can "pan" the map, and when I go over a
marker, A popup appears, and when I go out of the marker, the popup
disappear.
That's ok, but after the popup has appear an disappear, now I can not
"pan" the map.
Maybe the popup has deactivated something.
Can anyone help me?
Thanks

Following Alexandre's suggestion, here's what I did:
... //in init()
map.addLayer(markers);
//add the main select (for regular popups)
select = new OpenLayers.Control.SelectFeature(markers, {toggle:true,
clickout: true});
markers.events.on({ "featureselected": onMarkerSelect,
"featureunselected": onMarkerUnselect});
//add the second select for tooltips:
var highlightCtrl = new OpenLayers.Control.SelectFeature(markers, {
hover: true, highlightOnly: true, renderIntent: "temporary",
eventListeners: { featurehighlighted:
tooltipSelect,
featureunhighlighted: tooltipUnselect } });
//the order in which you add these lines seems to matter!
map.addControl(highlightCtrl);
map.addControl(select);
highlightCtrl.activate();
select.activate();
...//support functions
var lastFeature = null;
var tooltipPopup = null;
function tooltipSelect(event){
var feature = event.feature;
var selectedFeature = feature;
//if there is already an opened details window, don\'t draw the
tooltip
if(feature.popup != null){
return;
}
//if there are other tooltips active, destroy them
if(tooltipPopup != null){
map.removePopup(tooltipPopup);
tooltipPopup.destroy();
if(lastFeature != null){
delete lastFeature.popup;
tooltipPopup = null;
}
}
lastFeature = feature;
var tooltipPopup = new OpenLayers.Popup("activetooltip",
feature.geometry.getBounds().getCenterLonLat(),
new OpenLayers.Size(80,12),
" "+feature.attributes.name
<http://feature.attributes.name>,
true );
//this is messy, but I'm not a CSS guru
tooltipPopup.contentDiv.style.backgroundColor='ffffcb';
tooltipPopup.closeDiv.style.backgroundColor='ffffcb';
tooltipPopup.contentDiv.style.overflow='hidden';
tooltipPopup.contentDiv.style.padding='3px';
tooltipPopup.contentDiv.style.margin='0';
tooltipPopup.closeOnMove = true;
tooltipPopup.autoSize = true;
feature.popup = tooltipPopup;
map.addPopup(tooltipPopup);
}
function tooltipUnselect(event){
var feature = event.feature;
if(feature != null && feature.popup != null){
map.removePopup(feature.popup);
feature.popup.destroy();
delete feature.popup;
tooltipPopup = null;
lastFeature = null;
}
}
function onMarkerSelect(event) {
//unselect any previous selections
tooltipUnselect(event);
var feature = event.feature;
var selectedFeature = feature;
var popup = new OpenLayers.Popup.FramedCloud("activeAlarm",
feature.geometry.getBounds().getCenterLonLat(),
new OpenLayers.Size(100,100),
"Loading...<img
src='http://$server/map/symbols/ajax-loader.gif' border=0>",
null, true, onMarkerPopupClose );
feature.popup = popup;
popup.setOpacity(0.7);
map.addPopup(popup);
//call ajax to get the data
loadDetails(feature.attributes.description);
}
function onMarkerUnselect(event) {
var feature = event.feature;
if(feature.popup) {
map.removePopup(feature.popup);
feature.popup.destroy();
delete feature.popup;
}
}
function onMarkerPopupClose(evt) {
select.unselectAll();
}
I hope this helps others trying to add this feature.
Thanks again for your help.
Regards,
Adrian
