When I started playing STO I was able to see all targets, however, that disappeared and I have to tab each one individually. I see all the targets that are out of my line of sight, but not IN my line of sight without tabbing targets.
So my question is how can I put it back so all enemies and ally within range are shown in target in front of me
aha! found it. Under Options>HUD>Enemies there is a drop-down/checkbox for names, health & box. Looks like the default was names & Box always (box shows distance), and health when targeted. Still no idea how it got turned off, but just check always & hit apply.
