Yeah, that happens... Jody still hasn't checked in the guppi-gnumeric
stuff, so there are some gaps.  It shouldn't cause any problems,
though.

It will create the Makefile, but won't build anything.  At least in
theory...

In what way?

Yeah, this isn't very flexible.  One problem has been that guppi's
"engine" hasn't been good about handling on-the-fly changes to plots,
(i.e. adding new elements, etc.) which means things have been pretty
static in terms of the layout.  This is why there has always been a
linear regression element there by default... it couldn't really be
added later.

The good news is that I've recently fixed this, and plots can be build
up or torn down while being displayed.  So this sort of thing should
be getting better in the future.

I agree that it is a bit strange, but it can be nice to "home" only
part of your graph.  i.e. you can "home" the x-axis but leave the
y-axis zoomed in.  Of course, the easiest thing is to just press the
"Home" key, but I guess the theory is to put everything on the toolbar
for the benefit of new users...

I original confined the mouse to the window in question during tool
ops, but this became annoying for things like dragging.  I figured
that there was no harm in this.

Go outside the frame in the print preview?  There is a bug in
gnome-print 0.20 that causes clipping to not work properly when
"printing" to a gdk-pixbuf.  That might be the problem.  (It is fixed
in CVS; the rumor is that gnome-print 0.21 will be released real soon
now.)

Yikes... that isn't supposed to happen.  Can you tell me the specific
sequence actions that trigger those warnings?
