No symbol gProofServer

Hi,

I'm using a simple macro to plot some information from an TNtuple, read
from a file. The second time I run it, a sequence of errormessages are
generated, like "No symbol gProofServer" and "No symbol gProof". Althought
everything seems to work out well, I think this shoudl be investigated. I
tried to do it myself, but I was soon lost in the code. Therefore, I send
you my macro (see below).

Regards,

Marco van Leeuwen.

I'm using root v2.23/09 and the TNtuple in the file is not extraordinary
large (5 variables, 105 Entries).

--- Macro.C

{{
  gROOT->Reset();
  TCanvas *c1=new TCanvas("c1","Canvas #1",500,500);

gPad->DrawFrame(2.5,0.8,40,1.7);
  TFile fin("vtx_cali_fit.root");

TNtuple *NT = (TNtuple*) fin->Get("NT");   // Leaving this line out or
putting it in doesn't change anything
  Char_t crit[50];
  for (Int_t
type=1; type < 4; type++) {
    NT->SetMarkerStyle(type+2);

sprintf(&crit,"type==%d",type);
    NT->Draw("mean:p",crit,"same");
  }
}}
