It only sends a mouse click (no drag) if you are holding down shift at the time and doesn't break follow etc

One thing I should have mentioned is it appears to only be viable if all your windows are the same ratio. For example I use 1920x1200 on my main and 960x600 on 4 other windows and it works fine but if your other windows are 4:3 the clicking will be off. You will also want to make sure all use the same UI scale.

Can be pretty handy for buffing if you have a mixed group too. Setup healbot on all PC's and have something like alt + right mouse set to each classes buff. You just go down the list alt + right clicking and each character has their healbot set with alt + right click to a different buff.

My example:
Paladin 1 has healbot alt + right mouse set to Blessing of Wisdom
Paladin 2 has healbot alt + right mouse set to Blessing of Might


An alternative to healbot could be to use Grid and Clique.

The ideal setup would be Clique and the standard party interface but as far as I can tell the party order is hard-coded which would give a different order on each window.

Does anyone have other idea's on getting around this? I really need to play around with ag_unitframes. I think it may be possible to setup a group using that which is in the same order on all PC's and could replace the normal party list for me.

Main character alt + right clicks party member #1 on healbot and both Paladin 1 and 2 will buff with the appropriate blessing.
