So I have this awkward problem with gTalk. Let's say I talk with someone on gTalk on the mobile. If I open up the laptop or if I'm already online on the laptop and start chatting there then the phone stops buzzing me with new messages. It knows that I'm now on the laptop. However, this only happens with some contacts, with others, it doesn't matter if I start chatting on the computer, the phone keeps behaving like I receive new messages and continues notifying me for each new incoming line, which is... more than annoying in a conversation. Anyone knows how can I fix this? How can I make gTalk realize that I'm now chatting with that person on the computer and that it can stop buzzing me?
