Weird behavior after a window swap

Hello everyone, I know I'm not very active on the forums as much as I used to be but that's because I took a break from multiboxing for a while and now I'm back. I used to use Keyclone over two computers but have switched to ISBOXER/Inner Space when I came back. I have to say that ISBOXER is one helluva great application. I'm very greatful that Lax takes the time to give it TLC.

I started 5 boxing again just before the release of MOP and I have been experiencing a strange behavior when I swap windows. I use one monitor and mostly use the default key maps that are created during the wizard. The behavior I'm seeing is that when I switch characters (swap windows by clicking in them), the character that I was just on stops getting mappings. It seems he targets my main's target but doesn't do anything afterwards. But he will accept other key presses for abilities that doesn't require a target like self buff or mounting. He also knows who the jamba master is because he does know who to follow when I turn on jamba follow strobe after I make the toon swap. The way I correct it is by turning on mouse and keyboard repeater and press my mount hotkey and then turn off mouse/keyboard repeat.

Has anyone seen this behavior?
