So you cannot login to multiple chars from same account? Program only allows me to login on 1 window. I cannot on the rest without disconnecting the first?

This is how most games work, they will not allow you to log in multiple times to the same account. You need more than one account in order to log in more than one character in Path of Exile.

So the software is just an improvement over alt+ tab? that's it?

How did you come to that conclusion after reading Lax's reply on the need to own multiple accounts in order to play multiple accounts? You've obviously got access to ISBoxer because you're on this forum, so... Does the software look like a glorified ALT+TAB program?

Clearly, you do not understand.

I don't if I should laugh or cry.

This is the main page of the ISBoxer wiki. It is also the web page that loads inside ISBoxer and so is readily accessible to all ISBoxer users. The "What is ISBoxer?" section clearly spells out the many features of the software and provides links to pages with even more information.
