I dont know or its a bug or not but it's the biggest annoyance i have.
When the program see a par file it open it, no problem yet and fort the most files it perfect.
But somethimes i don't want that the program open the file and i want to run the quickpar program self.
When i want to kill it (delete) the progrom still continu with the file, i have to close the program and start it again to kill it.
