Cursor broadcasting is across several PC's, octopus (as far as i know) doesn't allow you to broadcast cursors to multiple clients on one PC.

For click broadcasting make sure you add left or right (or both) to a clicks profile under the clicks tab. Make sure you enable clicks to be passed, I added a hotkey to toggle it that was close to my AoE buttons for ease of turning it on and off.

I'm using 1.3.5 i believe.

Good luck
