crash when enabling metronome

Hi,

I'm on RB 7.0.9 on a windows dell inspiron 13. 

In export mode, with a single deck open and playing a track, when I enable metronome RB will at random instantly crash. When this happens it tends to continue happening after i restart the application. When I enable the metronome when the track is paused (not playing), then press play, I have not experienced app crashing.

Hope this bug can be resolved soon! 

Thanks

D
