[ROOT] no TView in current pad?

From: Tom Roberts (tjrob@fnal.gov)

When I try to "ZoomMove" in a 3-d drawing, I get the message "Error 
in <TAxis3D::PaintAxis>: no TView in current pad". But as far as I can 
tell I have a TView in the pad. Moreover, on some systems I get this 
(Root Version 3.02/07 10 January 2002 on RedHat Linux 7.1 console) but 
not on others (Root Version 3.01/06 12 July 2001 on RedHat Linux 6.2 
via remote X terminal).

How can I avoid this and be able to Zoom in on my drawing?

Also, somewhere I saw an "UnZoom" menu entry, but can no longer find it.
Where is it? (or where did it go?)
