Extra check before closing the program

[HaraldToepfer-OG]

I just had the idea that it would be a "nice to have" feature if the program would ask if the user really wants to close it.

Other than that, still works apsolutely flawless, even with 3GB catalogue file...just takes some time :-)
Absolutely LOVE your nifty program!

Thanks! Glad you're finding it useful. If I ever get around to a new update, I'll try to add that in.
