Is there a way to lock keyboard to one game window? I will be clicking the other game
window but I do not want my keyboard to send any clicks to that windows and I would
Like to be able to continue the rotation while click healing.

For anyone interested in this topic this please be aware that it is also being discussed, at least from a wow perspective, in this thread:

That is the only possible solution path that I know of so far and is specific to WoW.

Would love to know of a solution to bind a controller/mouse/keyboard/keypad/keystick to a given windows window (any window or any game window) as that could really help limit overhead from extra PCs/VMs/Multiseat-Desktops/etc...
