Last night I was fighting Belial on Hell, and my friend died in the top-left corner of the platform behind him. Every time I tried to click his gravestone to res him, I would simply attack Belial instead (even though my cursor would change to the "res player" hand). I tried zooming in with Z as well, but that didn't make a difference.
This has happened other times too, but its always been on bosses that move around, so I could kite them away from the body then run back and res.
Is there any other way to resurrect a player other than clicking their gravestone? Or failing that, is there a way to tell my character to not attack when clicking, so I can click on the gravestone?
(As a side note, I did finish killing Belial all by myself as a tanky-monk, even if it did take me 5-10 minutes since he had about 75% life when my friend died!)
