as far as I am aware, the recommended procedure is to create one infowindow and change its content and position with setContent and setPosition (unless you want multiple infowindows showing simultaneously).
from what I can tell, overriding an infowindow's contents removes the previous contents from the DOM. But it means that once set, there will always be one lot of contents in the DOM. It would have to be a very large contents for it to make any real difference on most computers, though. dunno if that's relevant, but I thought I might mention it. -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
