My addEvent replacement now supports the full emulation of W3C standard cancelBubble and stopPropagation in event capture and bubbling mode in browsers that don’t support W3C events (IE, Opera).

Here is a test case. If someone can break this and help me find any bugs I’d be very grateful.

Seems to work in Opera, IE5, IE5.5. IE6, Firefox 1.5, Mozilla, NS6.2, NS7.2, NS8

Will test it in Safari later, should work fine in but that browser has bitten me in the past.

    // If we have a native version
    if (p_event.stopPropagation)
    {
        // Then use it
        p_event.stopPropagation();
    }
    else
    {
        // Simulate it - the rest of the simulation code
        // will interpret cancelBubble correctly
        p_event.cancelBubble = true;
    }
