windows 7 64 bit, freezing up entirely when maple is left idle

my maple works fine on idle. I get dc'd every once in a while, but i'm not on often enough to notice. What i dislike though is the fact that windows mode likes to dysfunction every now and then. the window randomly teleports (for lack of a better word) from the center of my screen to the top right hand corner. I assume that's a window's 7 thing. If they'd just copypasta'd Nexon Korea's client, it would be perfectly fine by now. I run 32 bit Win 7 btw.

Rnadom dc's are common for me. especially at boss runs >.> I can't make mesos boss running if i get DC'd everytime i go. DC= unreliable pc = no accept to boss runs= no mesos= me poor.
