Odd rotation behavior

I am having a problem with this model in progress that I can't recall having previously (though it behaves the same way if I revert to MoI 3).
I can't seem to spin it easily. I want to be able to easily see the right side (right as in the posted view) but I can't simply spin the view so that this face will show in a more or less upright position.
It may be because I used the 'top' view to do the front elevation but I don't understand why this would make a difference in a 3d view.
Any thoughts?
cheers,
eric
