InDesign switched my palette layout without asking
I'm writing almost weeping with frustration. I'm in production mode on a book, and all of a sudden I opened one of the documents and InDesign had changed my workspace palette layout, which I've been using for years, into the format shown in Screenshot 1. I don't want it like that! I never asked it to change! (Pardon my venting.)

It used to be set up so that when I clicked on, say Paragraph Styles, it would open next to the worksheet lineup as in Screenshot 2 (where all my Para Styles would be displayed vertically). I can't give a screenshot of that because it's no longer the active layout.

Why would it do this, and what the heck do I have to do to put it back the way it was? I can't just reset it, because I'm pretty sure that would mean I'd have to recreate the workspace from scratch.
Please, if anyone can help me figure out how to change the layout, you'll be my best friend.
Thanks,
Susan
