So, my bf and I are both running into the same problem: our healing macros occasionally go berzerk and heal us instead of our targets. He's SCH, I'm WHM, and our spell macros are more or less the same:

/ac "Healing Spell" <mo>
/ac "Healing Spell" <f>
/ac "Healing Spell" <t>
/ac "Healing Spell" <tt>

We do not have <me> anywhere in the macro.

Sometimes, however, after going through the spell animation, the heal ends up hitting US instead of our intended target. This happens with mouseover on character models, nameplates, and the party list, and even when we have the intended recipient either targeted or even Focused.

Has anybody else run into this? It seems to happen at absolutely THE worst times!

Thanks for your help.
