   Error during release build:  Unresolved external symbol
  Hello.  I am trying to set up a project with Haaf's Game Engine.  I have managed to get a skeleton app built under debug mode.  However, when I try to build for release mode, I get an unresolved external symbol error.  Is there any reason this might be happening?   
  Post the error message.   ;  Have you all the libraries you depend on listed in the "Release" configuration? If so, please post the actual error you have encountered (use copy and paste).   ;  Doh!  I thought that the configuration I selected was for both build configurations.  I just added the libs to the release build configuration and it worked like a charm.  Thanks!
