Honestly I'm necroing this just to say "HOLY SH*T!! " With the utmost respect of course, I just bought a 4 port KVM today and I'm waiting on it to be delivered, and then I'm stumbling around looking for a way to box my three pcs, and this thing shows up and I tried it out and was essentially mind fucked lol. I've only had it bug on me twice so far, when i was bouncing from my media laptop, to my custom built desktop, then to my mini laptop, the mouse flickered and didn't transfer back to mini, but nothing a redrag didn't solve, But this is an amazing program and I only wished I'd found it sooner, I've yet to multibox with it, but so far4 it seems like it's gonna be great. I just don't know how well it will do with sending commands to background applications like HKN has issues with.
