"Delete from library" pop-up

[jez12]

When deleting songs from the "Now playing"-list, I got a pop-up asking if I want to delete the file from the library or also from the computer. I chose "Delete also from library" and then I checked the box "In the future, do not show this dialog". But now I don't want it to delete the songs from library. Is there any way to get the pop-up dialog to show up again? I searched through the options but couldn't find it. Reinstalling MediaMonkey probably does the trick but is there an easier way? Thanks.
