Try this ("root [0] .x blah.cxx"):
----------
void blah(void)
{
  TPaveText *p = (TPaveText *)0;
  
  Float_t x[3] = {1,2,3};
  Float_t y1[3] = {10,20,30};
  Float_t y2[3] = {11,22,33};
  
  TGraph *g1 = new TGraph(3, x, y1);
  TGraph *g2 = new TGraph(3, x, y2);
  
  TMultiGraph *mg = new TMultiGraph("MM","MyMulti Pad");
  mg->Add(g1);
  mg->Add(g2);
  
  TCanvas *c1 = new TCanvas();
  c1->Divide(1,2);
  
  c1_1->cd();
  mg->DrawClone("A");
  g1->Draw("L");
  c1_1->Update();
  //if ((p = ((TPaveText *)(gPad->FindObject("title")))) != 0)
  //  {
  //    p->Clear(); p->InsertLine(); p->InsertText("First Pad");
  //  }
  c1_1->Modified();
  
  c1_2->cd();
  mg->DrawClone("A");
  g2->Draw("L");
  c1_2->Update();
  //if ((p = ((TPaveText *)(gPad->FindObject("title")))) != 0)
  //  {
  //    p->Clear(); p->InsertLine(); p->InsertText("Second Pad");
  //  }
  c1_2->Modified();
  
  c1->Update();
  
  return;
}
----------
Then replace "DrawClone" with "Draw", to see the proper result.
My ROOT is 3.02/07 on a RH6.2/i386 with egcs-1.1.2
