iTunes remove track from Library pop up

[MightyB]

Hi all...quick one here...

Once upon ago there was a pop up when I hit "delete" to remove a track from my library. After awhile, I checked "don't ask me this again"...so now it does not pop up anymore...

But now I want it back...as my fat fingers have accidently hit "delete" a couple of times in iTunes...

how do I get it back??

thanks!
