Hi Ivan,
This has probably nothing to do with the postscript output.
Could you try removing the ps statements, just drawing on the screen.
Unfortunately, you do not mention which version of ROOT you are using.
My guess is that you use an old version before the TVanvas.Draw/Update memory
leak was corrected.
Could you try with the pro version 3.01/06 ?
