It was. I started the first tutorial example and got this "hello,
world", and then I looked into the menus.
Then I searched "root files" but this was empty (grmpf).
At some time, I got a core dump (Linux/lesstiff 0.77). I restarted
root and ... ofcourse: the same way run the hello-world example from
the tutorial (I didn't read much more there :-(), and the root file
(created with h2root) was there in a subdir
.../home/ole/Root/j123.root
But, when I clicked at one of the left buttons, this icon vanished and
I didn't get it back. So I had to restart it again...
In the meantime I got the mail that I can use "TBrowser B", ok this is
faster.
Then just clicking on the directory name, then on the file name and
there I got my hists.
Maybe, the root tutorial should (for stupid people like me) not start
with programming but with a chapter "How can I explore my histograms
with root?". This should contain:
- h2root usage
- TBrowser B
- where to find the files I want
- just the basics what happens with the left, middle (???) and right
click of the mouse.

The hists go from (x axis) -500 to 500. The interesting region for me
in only -10 to 10.
