Traditional DVI viewers are dedicated, and don't require the
".dvi" suffix. OK, Okular does require the suffix. Fixed in CVS.

I was going to say "No", but that's not entirely true. It depends
on which gnuplot "terminal" type is being used to display the 3d
plot interactively on the X window system. In current gnuplot
there are two possibilities, the x11 term and the wxt term
(WxWidgets). Up till now I've been forcing use of the x11 term,
since when I last checked wxt was too slow and jerky at rotating
the plot. But I see that's now fixed, so I've enabled wxt.
Anyway, the x11 driver needs a controlling terminal, so we can't
get rid of that little box, but wxt works fine without. Bottom
line: if your gnuplot is sufficiently up to date you won't see
that little terminal window again.

The error message is perfectly accurate (triplication nests
duplication) but it's not appropriate. There's no reason you
shouldn't be able to graph a variable against itself in 3
dimensions if you really want to. Fixed in CVS.
