Syntax highlighting not working

void TestMethod (int myInt) {

     int myNum =0;
     myNum = myInt *2;

     return myNum;
}


I have got this method as shown above. "Color identifiers" has been turn on in ReSharper settings, I have manually set "ReSharper Local Variable Identifiers" and "ReSharper Parameter Identifier" to some color (say red), but it is not working, i.e. both myInt and myNum are not in red. They used to work in ReSharper 4.x.

I am using ReSharperSetup.5.0.1659.36 with VS2005 + SP1.
