@BetterRed - Thanks for the suggestions, but they don't seem to have anything to do with this problem. The setting you mentioned is turned off because I like to look at new duplicates and determine whether or not the newer copy is better that the existing one. I
do get the dialog box that states that 'The 1 selected book(s) will be permanently deleted.....' At this point when I click on 'OK' the
entire folder for the author is deleted. It's as if I had all of the books for the author selected (which I don't) but to add to the confusion the dialog box definitely does say '1' (one) book will be deleted.
I've installed the latest update (2.41) but the problem is still there. BTW, I am using the 64bit version on Windows 7.
Any other suggestions?
