What to do if a game window disconnects??

Every once in a while my Aion client crashes, just one of them. And seeing as I am BRAND new at multi-boxing the only thing i know how to do is to close all the windows and restart. Which takes awhile for my comp and drivers me bonkers. Is there a way to reload just one screen? Sorry for what is probably super basic question, I have only been doing this for 4 days but am already in love and dreaming of what other teams to make, and games to try it in!

Thank you very much in advance for any and all help

Just select (launch) your team again, without closing any of the ones still up, and it will fill in the missing windows.

Ty very very much Sir!!
