I have a problem that I believe must be connected to my installation of VS2005, as my co-workers don't see this problem. I have a solution with 4 projects. The project in question is a C++ project using MFC. I have an include file used throughout the project with various definitions for conditionally compiling the software. I have made a change to this include file removing a definition, cleaned the solution and recompiled everything, but the software contains the software associated with the previous definition. If I query where that variable is defined, VS2005 takes me to the line following the deleted line. Again, this is not happening on other installations of VS2005.

What might be wrong with my installation? How can I get the compiler to see these changes?

Precompiled headers could be one reason.
