Here is the simple trick to find the friends who are online in Google talk but appearing offline.
Follow these steps to check who all are in invisible state.
- Open the chat window by clicking your friend’s name
- Click you friends name and select “Go off the Record”.
- Send some message to that user.
- if you get the feedback from gtalk that “User is offline and can’t receive messages” in red color means that the user is really offline.
- But if you get no response that means that the user is appearing offline and in invisible mode.
