  Hi Rooters

I was working on d0mino (D0 machine at Fermilab) and suddenly I am no
longer able to write histograms to file which used to work few days ago.

  fout = new TFile("fit_quality.root", "recreate");
  fout->cd();
  for( box=0 ; box<12 ; box++ )
  {
    h_slope[box]->Write();
    h_inter[box]->Write();
  }
  fout->ls();
  fout->Close();

The instruction fout->ls() gives only

TFile**         fit_quality.root
 TFile*         fit_quality.root


Also, when I read another root file, I have the diagnostic

WARNING, class:TProfile StreamerInfo read from file:slopes.root
        has the same version:3 than the active class
        but a different checksum.
        You should update the version to ClassDef(TProfile,4).
        Do not try to write objects with the current class definition,
        the files will not be readable.

I am not using any TProfile there!!!

                       Help

                             Thank you
