Inspector still showing "unused declaration" results after it's switched off

I'm running IntelliJ IDEA 13.1.4 Ultimate under the 30 day trial.

I have many many public methods in classes that aren't presently being called and I don't want the "unused declaration" to be searched for during inspections.

I've disabled it by unchecking it in the inspections preferences and re-run the inspector, but it still finds these problems.  I've re-enabled it and re-disabled it and re-run the inspector mandy times.  I've tried restarting intellij too.

Is there another setting I need to switch off to disable these, or is this a bug?  Can anybody else turn this off with this version?
