* method.
*
* Example:
* (code)
* popup = new OpenLayers.Popup("chicken",
* new OpenLayers.LonLat(5,40),
* new OpenLayers.Size(200,200),
* "example popup",
* true);

* map.addPopup(popup);

* for all other events, though we have to do so carefully,
* without disabling basic html functionality, like clicking on
* hyperlinks or drag-selecting text.
