InDesign CS5: Zombie panels

Question

I've had this problem with CS4 but it seems much more persistent (and annoying) in CS5: Panels that insist on reappearing whenever you switch workspaces, no matter how many times you close them.
The panels that appear are library panels and the Sample Buttons panel. This happens every time I switch workspaces and often when I first start the application. The library panels sometimes reappear after being dormant for weeks. To my knowledge, I've never intentionally opened the Sample Buttons panel.
I've done all the usual things. I've deleted my user preferences, restarted InDesign, rebooted. I've gone through each of my workspaces and deleted all of the unwanted panels individually, then resaved the workspaces. More than once. I've even deleted my workspaces and rebuilt them from scratch. But the panels continue to pop up -- usually right in the middle of the desktop.
The library panel problem can be fixed by deleting or moving the library. But my libraries live in certain locations on my hard drive for a reason, and it seems silly to keep moving them just to prevent a problem that shouldn't be happening in the first place. (Sort of like playing InDesign Whack-a-Mole.)
Anyone have any ideas on what's going on?

You don't mention your OS, so I don't know specifiacally where to send you, but I'd try closing ID, then renaming the InDesign SavedData file (you'll find path information in Replace Your Preferences )  and then I'd go to your user library or profile and find the workspaces folder and delete any XML file with the word "current" in it, then relaunch ID
