i have an htc hero and google talk has worked great for a year and a half. but now...when i haven't used my phone for >5 minutes if i go to google talk everything is greyed out as if i'm not connected. at this time, when i am logged into gtalk on a different account on a computer my android phone google talk account is not shown as idle (the icon is green). if i send a chat from the computer to the phone, the phone does not receive it. however, if i go to gtalk on my phone, in a few seconds it becomes active (so not greyed out) and i receive the chat. so this means that if i am not actively using gtalk, i don't receive messages until I open gtalk! this has only been the case for a couple of weeks...but i really depend on gtalk! i have tried restarting my phone. the weird behavior occurrs whether i am on 3g, edge or gprs. gtalk is set to automatically connect and not to go to standby when the screen is off. please can anyone help?? thanks!
