I'll give that a shot! Thank you very much

I have (what could possibly be rather silly) question. When I'm on a Mu* If I sit idle for a few minutes, I notice that when I type the following happens:

1. Nothing gets sent to the game and the screen just sits there..
(I solve this by manually disconnecting from the world and reocnnecting)

2. I get a disconnected message in the input window.
(This is resolved by just reconnecting)

I was wondering if there was a way to prevent this from happening? So if I say, leave my computer to grab a drink and a nke lunch, I don't come back to being disconnected?


Thank you in advanced!
