Mouse not working

Okay, this only happens with Swordsman Online. I have tried multiboxing with Marvel Heroes, and Path of Exile and it works perfectly. I can get multiple clients of Swordsman Online up with no problem, I just can't click anything. I have the box ticked so that the game believes it's in the foreground and I have made sure all resolutions aren't messed up and the mouse lines up perfectly. Is there anything I am missing?

Yes it sounds like you're missing that you should be on the development build of Inner Space for this game.

Right click IS, select Patcher, tick "Download development (test) patches" and then close and restart Inner Space to let it patch up. You should also be on the latest ISBoxer for best results -- go to ISBoxer's Help menu and select About ISBoxer. If it has a new version, update with the link provided there. If you updated this way you should go back and do the Quick Setup Wizard again since Swordsman Online has been added to the drop-down with custom Virtual Files (though you can also add those using the Virtual File Wizard).

I did what you said to do and now it doesn't even start the game anymore :S
.:Edit:.

I should be more specific, I get the arc launcher to work, but when I click on play now, the arc launcher minimizes and doesn't load swordsman online's launcher. Any ideas?

Thank you for helping me out!
