Tabbing is not working

If you are using the tab key to move through controls in Anytune and some controls are skipped you can try changing your tabbing behaviour. 

Tabbing behaviour can be adjusted in:
Mac OS System Preferences > Keyboard > Shortcuts : Full Keyboard Access 

Setting it to "All Controls" will allow you to tab through more controls.
It does have side affects, which can be annoying. The space bar won't Play/Pause when you have a control selected.   

You can use Control-Tab to move out of a text box.
You can toggle between these mode Ctrl-Fn-F7 but it can still be painful.  

The focus behaviour on MacOS is sometimes confusing.
