Hide when Compass Hides

[Azbandar]

Ok, I've hit a wall on this one. I've seen it done many times, but I can't figure out how to hide my AddOn UI when I enter a menu/chat/inventory/bank. I've seen it linked to hiding when the compass hides, but I can't figure it out for the life of me.

Anyone care to make a newbie feel like an idiot!?

Thanks!
