if you right-click instead of left-clicking using either the scene rotate tool or the key-shortcut (3) it does a bank rather than a heading change. Command or Control-Shift-Z is the undo for camera moves, just do that or if it was a real camera and not the default one you could also go to it's Coord tab and change it there.
GREAT! Thanks... FIXED!
I am on a mac pro laptop and I don't use a mouse. I must have put both fingers down at the same time when I rotated the object. It was frustrating the hell out of me. Thanks for the help.
