The point is - there is NOTHING drawn, even the canvas itself.
I mean, the "new TCanvas(...)" doesn't draw anything.
And later the "c->Draw()" doesn't draw anything.

Well, the "mycancas.root" looks perfectly fine.
Is it possible that because I link my Geant4 application with root
libraries (and not opposite) something important doesn't get initialized ?

I need (from time to time) to "c->Draw(); c->Update();" in order to
"refresh" the canvas.
Thanks in advance,
Jacek.
