    Tricky javascript/activex object problem

    The following script if run in Internet Explorer should
    display a thumbview of a webpage that you point it to.
    To test it, replace test.htm with a valid html file.

    The problem I'm having is that I can't get onclick to
    fire on the rendered Thumbview object. What's strange
    is that onmouseover fires. Can anyone see a way?

    <html><head><ti tle>test</title></head>
    <body onload="Init()" >
    <a onclick=alert() href="file:///C:/test.htm">
    <object id="Thumbview"
    classid="clsid: 1D2B4F40-1F10-11D1-9E88-00C04FDCAB92"
    width=120 height=100 onclick=alert() >
    </object><br><br> this works
    </a>
    <script>
    function Init(){
    Thumbview.displ ayFile('C:\\tes t.htm');
    }
    </script>
    </body></html>

      onclick and ondblclick just aren't honored by that ActiveX
      component. You can probably get onmousedown working, you'll just
      have to set it up so that it doesn't fire repeatedly.

      Something like:

      Thumbview.onmou sedown = function() {
      if (!this.mouseDow nFired) {
      this.mouseDownF ired = true;
      // do whatever
      return true;
      }
      return false;
      }

              Hi Grant,

              I discovered that onmousedown works. Also in conjunction with Overlib which is pretty cool.

              I haven't done anything to ensure that it doesn't fire repeatedly, but I haven't found that to be a problem. Can you tell me what could cause that to occur? Thank you

                  By "fire repeatedly" I mean that the native behavior of the
                  operating system causes an event like "onmousedow n" to fire over
                  and over again at say, 500ms intervals because the native
                  behavior of the operating system sends an event every 500ms when
                  a mouse button is held down. If the onmousedown event doesn't
                  fire repeatedly if you hold the mouse button down then it's fine.
                  I wasn't sure if it did. Using an alert() to test made it hard to
                  determine if the event was firing repeatedly.

                  Good examples of "repeatedly firing" events are "onkeydown" or
                  "onkeypress ", which _do_ fire over and over again when you hold a
                  key down. A simple example of this is (IE only):

                  <form>
                  <input type="text" onkeydown="putI nTa(this);">
                  <textarea name="output"></textarea>
                  </form>
                  <script type="text/javascript">
                  function putInTa(inp) {
                  inp.form.elemen ts['output'].value += window.event.ke yCode;
                  }
                  </script>
