Since when is a program allowed to decide to delete my information on its own accord? If not me, who authorised this? Not me. Really that kind of threat of deleting documents is completely unacceptable. It implies that I, the user, don't have any say. That I must make this decision right now. Because I have nothing better to do. That the computer cannot simply store these documents and restore them later when preview reopens. (Which it most definitely can) Its just lazy developers, or, much more likely: just bad ux.
