Refactoring seem to search for references in unnecessary places

Hi

I'm working on a web application using ASP.Net, on this particular project we use a large third party javascript component library. Of course we never modify code in this component library to references our application code, and I've made sure to configure resharper settings "Search and Navigation" and "Code Inspection" to exclude the folders which contain the components, but this doesn't seem to stop resharper refactoring functionality to search through these files during certain refactorings and cause it to run unnecessary slow. Is there additional settings to change this behavior? Or is this a limitation in Resharper?

Best regards,

Kaveh
