NF-Fixer 3.21

This is a little application that will fix some problems with Navy Field.
It allows you to:
- Continue firing while rotating, converging and elevating your guns without having to keep whacking the space bar.
- Select aircraft groups and add, remove, launch and return aircraft with keystrokes.
- Terminate Navy Field with a key-combo, or automatically if it hangs.
- Start the Navy Field launcher and then Navy Field with a single click.
