Selecting "loop playback" interrupts audio?

[millerworld]

I am investigating the use of an LE system to run simple backing tracks in a live situation.
One of the things I am experimenting with at the moment is being able to let (for example) an instrumental bridge run on a loop until the band want to move into the chorus.
Each time I hit <shift>,<apple>,<L> to toggle Loop Playback mode, there is an interruption in the audio playback.
Similarly I get a glitch if I move the loop locators.
I really hope I'm missing something simple and there is a way to do this.
Any ideas folks?

Thanks.
Miller.

Ableton Live maybe a better option for making 'on the fly' changes in a live performance situation.
