stop and play button both greyed out

[billyo]

i did a private show last night, ( just in time to try my new Mackie SRM 350v speakers )and i had Hoster on auto mode, had a few on the playlist, the singer decided not to continue singing, since she couldn't follow the the lyrics while being hilighted, and i noticed that both the stop and the play button are greyed out, and i couldn't stop the song playing, i had to wait for the song to end.when the song ended i switched to man. mode, clicked on the next song, stop button turned red and play button turned green, i havent noticed this before,since i never had someone quit at the mid. of a song. i was just wondering if those buttons are supposed to be greyed out on auto. mode..
