Why does input manager keep settings for all projects?

And more importantly how to stop it. When loading a new project with different input manager settings i notice it has copied across all the settings from the last project, essentially messing up the current project. The only way to make it work is to re-do everything in the input manager, then this in turn messes up the other project.

I have to be honest its a bit of a pain and other than just working on one project at a time (which is very difficult when doing lots of tutorials and testing other things) i dont have a solution for how to save input manager settings to just the current project.

Does anyone know a way around this?
