Tried deleting the QtCreator Preferences files (All of them) but that did not 
help. I tried LLDB from the command line but did not figure out how to set a 
break point. (I have never done LLDB from the command line) but I will work on 
that one just to make sure. 

I will also try doing a complete clean build of my project.

Thanks
Mike Jackson
