Messed up my tabs/slider

[platin465]

I was installing themes & clocks & stuff, now the slider background tab is in front of the currently selected item instead of behind. Two questions:

1. How do I fix this short of hard reset or using the touch diamond config utility to restore the screen (for the umpteenth time)?
2. What is the proper terminology for the item I'm having a problem with?

A suggestion (I didn't see this in the FAQs, although maybe I missed it):

Add a picture to the FAQ outlining what each item is on the phone so that when someone asks a question, they'll know what to call the item they're having an issue with. It's just that I've read various posts throughout this site where people are referring to one thing and people think they're referring to another.

Oh, and if it isn't covered already, could someone outline how to change the TF3D home screen's wallpaper in the FAQ? That's one of the things I see people asking over & over in the post your homescreen pages.

Thanks!!
