Ah, okay. I made a repeater region and deleted step 1 in all my healing macros. This is a bit better, but it still leaves my healer's cursor somewhere right next to the party window after I move my cursor out of the region. That means that someone who happens to be standing in that area will get my heals instead. Worse yet, the cursor seems to have some momentum upon leaving the window, so the faster it's moving, the further from the party window it comes to a stop.

Is there a way I can get the healer's cursor to park in a safe spot (on top of the minimap or something) when my cursor is not in the repeater region?
