That's normal, it doesn't mean something is wrong, it's just the floating 
filtering mechanism that uses that exception.
You can disable notification of this excpetion in the Visual Studio IDE (don't 
recall how exactly, but look under the Debug menu).

Are you running a debug version?
Are you running it from within the IDE?

Those are likly causes.
