Cannont resolve symbol '....'

Hi

I am using Resharper version 2.5.337.0 together with Visual Studio 2005.

I have a web project that has two web services as web references (file 2)

When I add a using directive to either of these ws the hightlighting displays this as an error. (file 1). If I use the intellisence then these web references are found.

I am able to build and run this web project as normal . If I uninstall Resharper then this errors are not diplayed.

Does anyone have any solution for this problem ?

thanks in advance
Peter
