"Move to recycle bin" dialog box not appearing anymore

Hello. My names Mike and I'm quite a computer savvy person. I've usually always been able to fix my own computer problems, but I'm stumped this time. I've been using iTunes since iTunes 4.0 was released. I love it (just about the only Mac product I do like).

Anyway, I like a clean computer, rid of music I don't like/listen to. Usually I just delete a song or 2 within the library and I always got 2 dialog boxes. Basically, 1. Asking me if I'm sure I want to delete it and 2. To keep the files or move to the recycle bin.

Well, recently, up to the new iTunes release 9.1.0.79, every time I delete a file from the library, I only get dialog box number 1, and not number 2. So it only deletes the file from the library, not the hard drive. So I've had to personally go into the folder and delete it =(.

I've tried to do some research myself, and it appears for the second dialog box to show it's face, the file you're deleting must be in the iTunes folder... well, that's ruled out. All my music is auto-organized by iTunes within it's own folder.

Does anyone have any solutions? I do not prefer third-party programs, but any help is greatly appreciated. Thank you in advanced.

OS: Windows Vista Home Premium SP2
iTunes: 9.1.0.79

Will post additional info if needed.
