    Hi Rene,
    May be I was not very clear in my statements. I mean that if I open 
file with any TTree object and try to draw it with void arguments session 
will be closed. To reproduce problem you need to type:

    TFile f("tree.root");
    .... bla-bla-bla ...
    f.ls()
..............
	tree;1   Tree with something
.............
    tree->Draw()

   And I've indicated in my prev. message that I'm using 3.03/09 (on AFS 
rh72gcc296).

   I'm sorry I can't describe problem in the first time.

		Best regards,
					Stanislav.
