Hi Eric,

I have tried to reproduce your problem with ROOT 3.05/05 on linux, but for 
me it works fine. I used the following example:


{
  TCanvas *c1 = new TCanvas("c1","Profile histogram example",200,10,700,500);
  hprof2d  = new TProfile2D("hprof2d","Profile of pz versus px and py",40,-4,4,40,-4,4,0,20);
  Float_t px, py, pz;
  for ( Int_t i=0; i<25000; i++) {
     gRandom->Rannor(px,py);
     pz = px*px + py*py;
     hprof2d->Fill(px,py,pz,1);
  }
  hprof2d->Draw("COLZ");
}

Let me know.

 Cheers,            Olivier
