Rockbox

On my Sansa c250 I found a bug in the metronome application. Everything seems to be displaying correctly on the application. You can set the tempo by clicking[select] or adjusting it with the volume controls. However when it comes to actually playing the metronome by pressing the play or pause button [ > || ] nothing happens! I am a musician and this metronome application is my main reason for putting rockbox on my Sansa c250. I installed it on my brother’s iPod and I absolutely love it. Getting a good metronome is not cheap, and I hate all of the ones I’ve purchased so far...
Any idea what’s going on here? Am I doing something stupid? I plan on using this to lay down some drum tracks next week if I can get it working :D
Any help would be greatly appreciated.
