I tried to zoom the histogram by mouse as was anounceed in
http://root.cern.ch/cgi-bin/print_hit_bold.pl/root/roottalk/roottalk98/2349.html
"Note that in the version 2.20, I have added an automatic zoom
facility. You can click with the left button on the position
where you want to start zooming and release the button where
you want to end zooming."
by Rene, but without success: left mouse button has no actions in case of
2-d histogram and has "move histogram" action in 1-d case.
What is wrong?
I use root 2.22/04 on RH6.0
