title: qrc file disappears using Qt and visual studio 2010
body: <p>I'm creating GUI using Qt in Visual Studio 2010. I've done quite a lot of job then I have added tab widget and subsequent rebuild ended with missing qrc_file.cpp missing and the file had really disappeared from it's directory. When I returned back to previous backup and added tab widget again problem appeared again. But It's strange because sometimes build with tab widget is successful, in this case the qrc file is deleted by something in the next build.</p>
  
  <p>Thanks for your experience! </p>
