Unfortunately (for me, anyway), that just doesn't work in my case. So, I'll just keep using WatchFrameRemover to hide Blizz's watch window. It's no big deal and I have no problem doing things this way. Actually, I didn't even remember that option being there, but when I opened Carbonites options, it was already checked. I don't know if that's the default setting for it, but I just don't remember ever setting it. (see my signature
)
One thing to note: I use absolutely no other questing addons what so ever. I have no need for them. I'm using Carbonite. (and have for the past four years)
