David,

I can't trivially replicate this error using Firefox (the platform that
I have handy). However, I do notice some things that aren't working as
you expect them. Specifically: 

  * minZoomLevel and maxZoomLevel need to be MIN_ZOOM_LEVEL and
    MAX_ZOOM_LEVEL. When I do this, I get the more-expected behavior
    from this map.

  * VE allows panning outside their 'world' within OpenLayers: you can
    prevent this by setting:
      mccontrol.map.restrictedExtent = new
        OpenLayers.Bounds(-180,-85,180,85)

With these two in place, I Get much better behavior with your map. This
might help fix your IE issue as well.
