Maple automatically closes

When another user signs onto my computer in a different user account, maple automatically closes after a minute or two, does anyone know of this problem or have a remedy for it? My sister needs to get on at night when I usually set up my shop, but whenever she logs onto her desktop it boots me off Maple, its getting annoying that I cant sell anything. =(

On your computer?
You switch users, which cuts the internet.

Solution: Get a laptop.

Are you sure? I recalled leaving AIM up and still being logged on before...

I think Gameguard does that on purpose. Not sure though.

ive switched users before, it left my game up, but this might have something with what the other person is doing, maybe anthor version of game guard running, does it give you an error? anything or does it just close, but if you get timed out ie internet droped you get an error

I think the problem is that ur computer ran out of ram or memory. or your internet is too slow to process maplestory AND whatever your sister was doing. I switched users before too and I know that I was running out of ram on my mom's acct, so when I switch back to my own acct, my maple was close.
