i've always had this weird problem - right from 4.0 up to the current version 4.3.
whenever i'm editing thousands of photos halfway, and when i reject photos along the way, i will clear them using ctrl+backspace. usually, it does delete all the rejected photos from disk successfully. however, i notice sometimes that it fails to delete the first rejected photo.
i have to manually delete that one photo thereafter. (and it works)
any of you encountered the same problem?
