DualView is a kludge to deal with applications that do not properly support dual monitors. Marine Aquarium 3 should no longer require DualView to run on 2 monitors. That should be a good thing! What else do you lose besides the menu bar on both screens when you get rid of DualView?

It would take a lot of programming effort, and the fish selection box in Marine Aquarium would have to be adapted to allow 14 or however many fish selections you're going to allow, to support the same background on 2 screens. The hardest part though is that the collision avoidance code in the Aquarium is hard-coded in basic math (according to Jim) instead of modular code written with calculus/physics/etc. and so cannot simply be adapted over to work with a different background. I think it's simply too much effort to do this on the 2D background when a 3D background is in development and that effort is then wasted.
