I really don't know that I understand what you're trying to do. It sounds like you are trying to use the Keyclone mouse passing to make your slaves interact with the same NPCs that your main is using. I really don't think that is the most dependable or feasable way to do that. As I said, Keyclone's mouse passing is not the same as adding a permanent cursor/mouse to every instance of WoW. Basically, all it does is go from window to window if I recall and loses its' accuracy if the windows are not al the same size/resolution.

If you did want mouse passing to work you would need :

Image 1 - "pass mouse click hotkey" You don't have a hot key here, it won't work without one. "Distinguish Left/Right Mouse click" from the info in image 2, it looks like you do want it to know the difference, so you would need to check that. "One click then off" probably needs to be unchecked for what you're trying. Beyond that, I don't know what to tell ya, I never got mousepassing to work accurately enough to make it something I was comfortable with using.

Again, your best bet for interacting on your slaves is :

1. Go into the default WoW keybindings. Set a key for "interact with target". I have the same key on all my toons so they all interact and open the window for Jamba to do its' thing.
2. Go into the default WoW interface under Mouse. Turn "click to move" on for all slaves.
3. Create a macro for "assist MAINTOOON" and bind it to a key that's easy to combine with the interact key from 1.

For me, I use ` and Alt-`. Run up to your target, hit ` and all slaves assist the main to get the NPC or mob targetted. Hit Alt-` and the main and slaves all open the window, try to loot the corpse, skin or whatever other interaction.
