gApplication with pyroot

Dear pyroot experts,
I want to draw some histograms with a python script. What is strange is that sometimes it works and sometime not, i.e. it will hang without drawing anything and I have to kill it by hand. I guess because the draw method is inside a loop?

-------------------SNIP---------------------------

for j in range(0,dim):

    can.append(TCanvas("can%i"%(j),NameHist[j],1400,1000))     app = gApplication
    can[j].Connect("Closed()", "TApplication", app, "Terminate()")     can[j].cd()        

    gPad.SetLogy()

    hframe = gPad.DrawFrame(float(Xmin[j]),1e-6,float(Xmax[j]),1)

    hframe.GetXaxis().SetTitleSize(0.04)
    hframe.GetXaxis().SetTitle(TitleHist[j])
    hframe.GetYaxis().SetTitle("Normalised Counts [a.u.]")
    CORS[j].DrawNormalized("same")
    DATA[j].DrawNormalized("same")
    CORS[j].SetTitle(TitleHist[j])

    CORS[j].Write()
    DATA[j].Write()    

    leg.Draw("same")

    can[j].Update()
    can[j].Modified()
    can[j].Print(dir+"/"+NameHist[j]+bdtcut+".png")
   

app.Run()

What is wrong? Any idea?

Thanks

A
