Enemy addon, clic through bars.

[Tholkienn]

Hi ladz.
I have an issue with this addon, and i don't manage to fix it.

When i clic a bar to select it, it's like i clic through the bar, so it select what is behind.
It's a real problem when i play healer...

Someone can tell me where is the option to fix that?

I try to look every option i can, but i don't see the one i have tick, who can do that...
