Aww you are so sweet to have done that, thank you. Really, I appreciate it!
Unfortunately, I checked the box, and eyes still moved.
I used the sliders above that about the eye movements (which seem to directly relate to the debug settings I listed at first post), as well, and eyes are still moving.
Maybe Firestorm broke this with their attempts to integrate it into their interface?
ETA: Installed another viewer to see if this is still a problem or isolated to Firestorm alone. Using debug settings eyes still moved. Apparently this is on the SL/LL side of things and not a viewer issue. =(
