[ROOT] Error: class,struct,union or type TProof not defined

Hello,

another (hopefully) trivial problem:

Here is LlrTupleInfo.C:

class LlrTupleInfo
{
public:
  LlrTupleInfo(TTree *ntuple)
  {
    TCanvas *c = new TCanvas;
    
    ntuple->Draw("mh"); 
    delete c;
  }
};


(I basically want to use Draw() to read the values from the ntuple after
some user defined
cut into arrays and I don't want to leave canvases lying around after
calling the constructor).

I do:
root [0]  .L LlrTupleInfo.C
root [1]  TFile *infile = new TFile("test.root");
root [2]  LlrTupleInfo *tuple1 = new LlrTupleInfo((TTree
*)(infile->Get("h7000")));

which works fine.
But trying to open a second file (or the same file again) fails:

root [3]  TFile *infile2 = new TFile("test.root");
Error: class,struct,union or type TProof not defined 
FILE:/tmp/filekBIxS1_cint LINE:1
*** Interpreter error recovered ***

I also saw the same message using h7000 (and infile->cd(); ) instead of
infile->Get(..).


Does somebody have a solution ? 


(I'm using  2.26/00 on Linux).


thanks,


Andre
