Hi Eric, i agree with you about the samples in HelloMaps, but the situation is quite different: in this case, removing the overlays (marker and markerClickHandler) does not depend on event but it's periodically scheduled in a timer. I've tried also with two vector: the first one is for the markers, the second one is for the markerClickHandler and then call the removeOverlay with this arguments. The problem in my opinion are: -) number of markers, beeing a tracking application, is not knows a priori -) the clearOverlays does not free memory with ie7 -) the issue is with the markerClickHandlerVector: in fact, commenting that, memory does not increase. As suggested some posts ago, I've recompiled the gwt-user commenting the opacity attribute in PopUpImplIe6... perhaps quite better, but however memory usage increases and increases.. any suggestions? thx, Michela
