[OpenLayers-Users] Scrollbars within popup? (overflow:auto)

[Nick Whitelegg]

I'm trying to create a <div> within a popup (associated with a feature) and 
set its style to overflow:auto so that it will scroll if the text within the 
popup overflows the div. However it does not appear to work - no scrollbars 
are created. Sample code:

data.popupSize = new OpenLayers.Size(320, 200);
 contentHTML = "<div style='overflow:auto'>";

            if (description != null) {
                contentHTML += description;
            }
contentHTML += "</div>";
data['popupContentHTML'] = contentHTML;

Is there any way of doing this? Alternatively is there a way of saying that 
the popup will be "as big as it needs to be"?

Thanks,
Nick
