(I apologize if this is in the wrong forum or has already been addressed. I have searched without success to find an answer.)
This evening while working with my books in Calibre, my cat walked across my computer. Next thing I knew, my book details pane was GONE! I have tried everything possible, searched, etc. and cannot figure out where on earth it has gone and how to get it back.
I'm guessing it's probably something simple, but it's beyond me. If anyone could help, you will have my utmost appreciation. (Sorry, you can't have my cat!

)
