Sonar deletes release but not debug version of program

I'm developing an application under MS Visual Studio Express 2008, and the release version is immediately killed by Sonar, whereas the debug version is left alone.  I have read some of the threads on Sonar, and its problems, but have not seen what causes the release version of a program to be deleted but not the debug version.  The only difference I can see is that the release version has the MS DLLs included in the executable, whereas the debug version doesn't.  Do I have to make it so my application depends upon secondary DLLs in order to be Sonar safe?

 

What else do I have to do to keep Sonar happy when I release this version of my app?  (A signing certificate is beyond my means at this point, so please keep the answers to programming features.)
