Have noticed recently that the HUD arrow disappears when in combat. Would prefer to have it on all the time, but have been unable to find a setting for it in the options anywhere.. Is this a bug? Currently using "Carbonite-5052"
You should probably update your version of Carbonite. Current Live version is 5.0591, and the current BETA version is 22.214.171.124.
That being said: There are a few things you can check.
If the Carbonite HUD is not locked, right click it and, in the menu, uncheck the "Hide In Combat" option.
If the HUD is locked, open Carbonites options to the "Tracking HUD" page, and unlock the HUD there. This is the only place the HUD can be locked/unlocked.
This is also the place for the "Hide in battlegrounds" option, and if you wish to see the HUD at all times, uncheck the option if it is checked.
After setting your options the way you want them, I definitely recommend locking the HUD in place. That way it can never be accidentally moved off screen, or just moved while you are in some intense combat to somewhere that is "in the way".
I hope this helps in solving your problem.
Ahhhh, the vagueries of the aging mind. Wait.... What was I saying?
