I fighter 2 doesn't save settings

[Air Ben]

I have the gripe that my preferences (muting both music and sound effects) are ignored each time the app is resumed (or after task switching!)

I don't have hardware buttons on my phone, but areas with sensors, so can easily switch by accident. It is most noticeable when switching to another app as ifighter knows they were muted: when I return the sounds start playing, but them upon entering the settings dialog, I can see both volume sliders sitting on mute!

To configure it to mute these again, they need to be moved to the right slightly and then returned all the way to the left again!
