I was just playing a .flac song that was not in the library. But I added it to the library while it was still playing from the original location. So (not thinking to stop playback) I went to delete the original location. I got an error saying that a file was in use. When I went to stop the song I stopped and minimized JRiver. That is when I got a blue screen. I am using Windows 7 Ultimate 64 bit. I have 12 GB of RAM, 2.8.Ghz Intel CPU (1366). Geforce GTS450 Video card. Xonar Essence STX PCIe Audiophile sound card. I am not sure if this is a bug with JRiver or my Video Driver? I'm using JRiver Media Center 17 version 17.0.50
