There's a few settings you ought to make sure are checked like Options-General-General-Hide and check Empty and Empty Buttons.
Sweet! Looks like checking the 'Empty and Empty Buttons' boxes did the trick. I could now move the pet panel to overlap the raid panel, and now I can see the pet panel right next to mine and click on it fine. Without those 2 checked looks like the empty raid panel was interfering with my pet panel. Thanks again.
