What version of Grid2 are you using?

r950

What game client version (windows or mac) and language are you using ?

8.3

What steps will reproduce the problem?

   1) Configure mouseover highlight settings for the current theme. When out of combat they appear to work correctly. 

   2) Enter combat (I was testing it on the training dummy). They still work correctly

   3) Take some damage and drop some health. Highlight no longer works. 

   4) Upon leaving the combat highlight still doesn't work. Unless you reapply the highlight settings again.

  
Did you try having Grid2 as the only enabled addon and everything else disabled?

No

Was it working in a previous version? If yes, which was the last good one?

I didn't try using mouseover highlight before as I've just discovered it
