In case anyone's interested in the outcome, for the sake of Chrome I had to 
put a setTimeout poll (hate it!) on the 
document.getElementById("appletId").status - for example: -

        var waitForAppletDOM = function() {
            if (window.console) console.log("in waitForAppletDOM");
            var appletStatus = ((chanG.status||undefined) == undefined) ? 0 
: chanG.status;
            switch (appletStatus) {
                case 0:
                    if (window.console) console.log("case 0");
                    setTimeout(waitForAppletDOM,250);
                    break;
                case 1:
                    if (window.console) console.log("case 1");
                    chanG.onLoad  = appletLoad;
                    chanG.onError = appletError;
                    break;
                case 2:
                    if (window.console) console.log("case 2");
                    alert("Applet is already loaded");
                    break;
                case 3:
                    if (window.console) console.log("case 3");
                    throw new Error("Error activating Applet");
                    break;
                default:
                    throw new Error("Invalid Applet status");
            }

Needles to say, Windows/Safari is a dead bloody loss :-( Also note that, for 
FireFox and Opera, if you do an "alert('some-debug-stuff')" from you 
"onError" handler the our browser freezes.
