Does Maplestory stay turned on when you computer is sleeping?

No, I get disconnected, but that's my own sleep-mode + laptop. Even without sleep-mode, sometimes, if I minimize my MS, and come back like 6 hours later.. I find out I somehow already got disconnected when I start seeing a bunch of YELLOW MapleTip messages all over my chat-box.
