aplay, vlc, Xfce launcher conflict

Hi All, Scientific Linux 6.2 x64 Xfce 4.8 I have a weird problem since upgrading from SL 6.1 to SL 6.2 If I have VLC open and playing music, when starting the following line from an icon in a panel 2 launcher, the line hangs at the aplay statement (no ding): sh -c "/usr/bin/aplay -q /home/linuxutil/KDE_Notify.wav; /usr/bin/wine "/home/tony/.wine/drive_c/lotus/123/123w.exe"" If I press "stop" on VLC, I here the aplay ding, and the command continues and completes as it should. Then I can restart my music. Weird though: I can run the above from a command prompt and it dings right on top of VLC (no hang) and the command completes as it should. Confused, -T
