Anyone know what might be causing this maps problem?

In the above, click the Maps heading in the Accordion. Does anyone know what might be causing the 开发者_如何转开发odd problem where only the top right of the maps shows? It fixes itself when you load up Firebug or Chromes Inspect Element feature.

All suggestions welcome :)

Try loading your map on click

$("#mapAccordionTrigger").click(function() {
        if (GBrowserIsCompatible()) {
            var lat = 53.559991;
            var lng = -6.799526;

            var map = new GMap2(document.getElementById("map"));
            map.addControl(new GSmallMapControl());
            map.addControl(new GMapTypeControl());
            map.setCenter(new GLatLng(lat, lng), 15);

            var infoTabs = [
                new GInfoWindowTab("Address", "4 Bed Detached Houses<br />From &euro;249,000"),
                ];

            // Place a marker in the center of the map and open the info window
            var marker = new GMarker(map.getCenter());
            GEvent.addListener(marker, "click", function() {
                marker.openInfoWindowTabsHtml(infoTabs);
            });
            map.addOverlay(marker);
            marker.openInfoWindowTabsHtml(infoTabs);

            var point = new GLatLng(lat, lng);
            panoramaOptions = {
                latlng: point
            };
            pano = new GStreetviewPanorama(document.getElementById("streetview"), panoramaOptions);
            GEvent.addListener(pano);

        }
});
