Try renaming it.

Could you update your source tree and try it again?

Correct.

Event selection is a work in progress and isn't integrated with window 
scrolling, so this could be problematic.

Do you mean editing the metronome or trying to turn it on?

That is correct.

This is not implemented, but we are working on it.

Thanks for trying this with the code in such a preliminary state.  I'm 
just trying to get a MIDI file loading and playing on all platforms at 
this point.

Try the suggestions above...

1. Update the code and rebuild.  You can copy the new jazz binary over 
the one in TestInstall/bin.
2. Rename the config file in your home directory so it isn't used.
3. Make sure the .alsa_input_device and the .alsa_output_device entries 
in TestInstall/share/Jazz++/jazz.cfg are set to -1 so you will be 
prompted for input and output devices.
4. Run the version in TestInstall/bin.

Let us know how it goes.
