Mac OS version 2.0.3 available now

this update fixes the previously identified issues with user preferences, saved results and the rhythm exercise.

For now, the levels available in the rhythm exercise are: Default, RCM Grade 1 through 3. More levels will be added soon in the next update.

The broken settings menus are now active, giving the user an option to temporarily over-ride the playback type in the chord and inverval exercises.
