Well I discovered something unusual this morning when I logged on to orkut, something which intrigued me but it might be just mountain out of a molehill.
The 'hidden' SWF or the 'transparent' SWF ie flash can been detected if you have a Mozilla Firefox with AdBlock addon installed. The SWF is at right bottom corner of the browser and can been detected coz of 'Adblock' button seen.
The swf is probably coz of google talk but no idea why it has been put up now and in this manner.
The info we get about the Swf is --- http://orkut.com/talk/datastore2.swf
Probably something which needs some research :)
