Hi Len,I stuck your code the following function definition but even thought the popup shows up it does not contain any information.
this.onLoadedMapbook = function(mapbookXML) {#your hover code
}
I changed the line setting the url to the identify.php like this to suite my local settings. var url = 'http://localhost/moosecache2/php/identify.php?';
I am not sure if there is something else I need to do to. I have seen it work on your site so it should work on my I suppose.

> Performance seems ok, you can try it at http://dev.houstoneng.net/geomoose.html. Hover over a parcel for 1 second and you should get a popup. It's different than passing over a marker in OL because the handler is triggered after a pause in mouse movement vs. going over the marker. The downside is there will be a lot of calls back to the server (could be an issue on a high use app) and in the case of parcels, the number of popups could get annoying to the person looking at the map. Might work better with point data.
