Draw either point or extent?

Hi all,

I'm trying to figure out how to use the Draw toolbar to allow a user to draw either a point or an extent.  I'm trying to use this for the identify tool.  I don't want the user to have to select either point or extent, I want the application to be intelligent enough to determine if the user has clicked a single point, or clicked and dragged the mouse to enclose an extent.  The problem I'm running into is if the Draw toolbar is in EXTENT mode, a single click starts drawing, and another single click finishes the drawing.  I want a single click to represent a point.  Is this possible?  Also, am I doing this the wrong way?  Is there a better way for the user to be able to identify from either a point or an extent?

This code seems like it would work, but since the Draw toolbar doesn't fire the "onDrawEnd" event on a single click if drawing an EXTENT, it doesn't.

var drawToolbar = new esri.toolbars.Draw(map);
    dojo.connect(drawToolbar, "onDrawEnd", function (geom) {
        if(geom.xmin == geom.xmax && geom.ymin == geom.ymax) {
            geom = new esri.geometry.Point(geom.xmin, geom.ymin, geom.spatialReference);

        // execute an identifyTask using geom


Thanks for your help.
