Hi Ron, My guess would be that it's an issue of near/far clipping. Personally I wouldn't mix orthographic projection with a general purpose camera manipulator as they are written for full 3D perspective views, and when you moving in and out of the scene in a orthographic view things won't work visually. The problem is a bit like trying use a hammer to screw in a screw, as much as you might try it won't work properly.
For application I use orthographic views for map, isometric or side elevation views where the viewer can move laterally but not into the scene and would be very careful about introducing any allowing free form rotation. If you want full movement in the scene you really need a proper 3D view for visualization to behave correct as end users would expect from a 3D environment, for this you really need to use a perspective view.
