ISBoxer weirdness

I'm having some weird performance issues that I didn't have until recently.

I solo leveled my first toon to 90 and decided that I'd go back to multiboxing...

When I mouse broadcast on my main screen, the mouse on my slave screens lags behind by 4 or 5 seconds. This hasn't happened before today (I pvp'd a bit when I wasn't leveling) I'm using the same settings I was before and even tried turning everything down/off. I'm a bit stumped :(

CPU is at 30% with 5x toons sitting in their home cities
memory is 52% (I have a ramdrive in there so I think WoW takes it up to 52% from like...30%)
GPU is at 39%

Nothing's choppy FPS is capped on the slaves at 30 and capped at 60 on the master - just really laggy :(

any thoughts?


edit: looks like keybroadcasting is behind as well :(
