Mouse sensitivity and PiP in Octopus

I have two questions regarding mouse sensitivity and PiP in Octopus.

First of all the mouse sensitivity. I use different resolutions on my monitors and when I move to another monitor using KVM the mouse is slightly too sensitive for my likings on the slave screen. This probably has to do with the reason that my resolution on the main monitor is higher. I know I can adjust the mouse sensitivity for the WoW client on the slave, but preferably I'd like to change it on the Windows level (but only when Octopus is running) so that it's also easy to use for other things. Is there a clever way to deal with this?

Second of all the PiP function in Octopus. It seems so simple, but I just cant get it to work. It doesnt matter what key I try, it never functions correctly. I.e. I set the PiP key for the main instance to F1 and the slave instance to F2, launch them both, then try pressing both F1 and F2 but nothing happens. What am I doing wrong?

There is an option on client/mouse for the mouse speed. This is set every time the mouse transitions to the client, the catch is WoW will set it to mouse speed 10 .. at least when you start WoW.. that's all.

Well, the PiP is suposed to switch the instance with the hot key with the foreground window, if its a window in the client box. Seems to work? no? (does here)

Ah great, didn't see that option yet!

As for PiP, it's a bit weird. It seems to work on some keybinds, but not on others. I can't really figure out why yet though. I don't have other keyboard hooks installed (though I suppose Microsoft Keyboard might have installed 1). Regardless, I got it working now for some other keys.
