I'm new to PHPStorm but very impressed so far; I've managed to get PHP CodeSniffer up and running (see below screenshot) and highlighting sniffs in the editor is working well and shows all issues (at least up to the 100 allowed!).
But when I perform "Inspect Code" on the source (shown in the screenshot running on a single simple file) there is only ever a single CodeSniffer warning (always the first issue). Other inspections seem to be working fine and returning hundreds of warnings across large code bases.
I've spent a while trying to plough through the settings but can't find a reason for this. Can anyone enlighten me?
