See in this screen for the standard raid frames I have some strange symbols sometimes.
Problem is, that for example the sha heroic macro will not work because the area around this icon seems to block mouseover commands.
So how to get rid of this - whatever it is.
Hm well using lots of addons; pitbull for unitframes atm.
I have this icon very often but it never bothered me until I wiped us at sha heroic because of it -.-
I had struck-through my text because you stated you were using standard raid frames. If that icon is persisting after everyone has been rezzed you're going to have to do a reload. That or look into updating pitbull, sorry I don't use it so couldn't tell you what the newest revision is.
