"Invalid "Target" error on clone

[Temor]

I assigned the following macros to the action bar on my alt computer:

button 1
/assist stonez

button 2
/cast smite

I always target the mob on my main using the TAB key, then press 1 to have my alt target the same mob, finally press 2 to command my alt to start casting smite on the mob. Initially, this work perfectly, but problem starts happening after my alt interact with any NPC. I thought keyclone on my main computer is not sending the right signal to the Alt computer, so I tried controlling my Alt directly from the Alt computer keyboard. but I still get an "invalid target" error on the Alt computer

At the same time, I also observed that the right mouse click on the alt computer stop responding, eg. can't activate the hearthstone in the inventory.

Both problems are gone if I

1.change the Alt computer from Full screen to windows mode or the other way round
2. terminate Keyclone on the Alt computer.

but they come back again after my Alt interact with NPC .

This sounds very similar to the problem that I have. It doesn't happen all of the time, but while playing, it just loses the ability to select anything from the inventory from the clone machines. My set up is much easier than the way you've got yours. I use ONE KEY press, the number 9, which does this:

/follow main

/assist main

/startattack

/cast (whatever spell I use for that clone as their instant attack spell)

/petattack (If that clone has a pet)

I do all that with one key press. It SAVES a BUNCH of time.



Now the way that I've found without closing down Keyclone or WoW, is just simply alt-tab to Keyclone and depress the button labeled 'override' twice. That fixes it for me.

Just a question for you, is your alt (clone) a healer? Can he do a heal? If so, when you lose the ability to select Hearthstone, can you still heal your main? And can you give your main buffs? Because I can't when this problem happens to me.
