Messages not being sent/received after 5 mins, timeout issue?
I've been using Messages since the Beta release and hoped this issue would be fixed in Mountain Lion. Whilst the app works well for the most part I have an issue with it seeming to stall or timeout after about 5 minutes of inactivity. As an example I can be having a conversation with someone and if I don't respond for 5 minutes and then try and reply my message is not sent and I end up with the red exclamation mark. I can resend it by clicking on the red exclamation mark but that gets quite annoying all the time. Also if the person I'm chatting to tried to send me a message during this stall/timeout period then it won't come through on my Mac until I try and send a message to them.
I get all messages send/receive fine on my iPhone and iPad and sometimes I'm only aware of a new message in the conversation when it flashes up on either of my iOS devices. This then prompts me to reply on my Mac as above and the message then comes through.
Is anyone else having this issue?
