[OpenLayers-Users] Allow marquee zoom outside of map div

[PORTER.DANIEL]

Hey list,

I'm using the ZoomBox control to allow users to marquee zoom in and out, accessed via panel-controlled buttons.  If you drag your mouse outside of the map div, the marquee disappears.  Does anyone know a reasonably simple way to allow the marquee to extend beyond the map div?  The API information for ZoomBox is markedly close-lipped: http://dev.openlayers.org/apidocs/files/OpenLayers/Control/ZoomBox-js.html

Thanks!
Daniel
