The rectangle zoom doesn't seem to work for me. Instead of zooming,
clicking and dragging the right mouse button draws a series of
rectangles which don't go away when the mouse button is released, and
no zoom occurs (see the attached screenshot). I assume it works for
you, so do you have any clues about how to debug this problem? I'm
using libfltk1.1-dev (v 1.1.9-6) on a Debian AMD64 system. Does
anyone else see this problem?
I checked it in anyway, since the other features work, and I'm not
sure whether this is a library problem, or some other problem.
Thanks,
