Flashing frames usually mean your RangeCheck and CombatFader modules are both enabled on the same frame, causing alpha conflicts. Disable one or the other.
while that fixed the problem yesterday i am configuring the raid frames today. oddly enough just one of 40 raid members is flickering (this time i am in ironforge and i am using the set-up functions (so i am not actually in a raid). Also, the target of the focus is flickering. With a white glow of somesort. All of the settings are okay and i left the set-up, so it does not bother me now... but what happens if i go AV this afternoon? Will that one raid member in group 7 flash again constantly?
