RhinoV8: Mouse in Perspective View does not respond

My mouse in perspective view does not respond in RhinoV8 as it does in my old RhinoV4 and the new RhinoV9WIP. What is wrong if the view &mouse option are exactly the same?

does not respond is not clear enough… does it not respond at all? or does it respond differently?

if not at all, try running the 4view command (may need to run it 2x)

if differently, can you give details as to how?

The problem is that, when I use the rotate view command in “perspective view”, it does not respond in each of the “Set CPlane” as in other versions of Rhino (RhinoV4 & RhinoV9WIP). Sometimes it does not follow the rotation indicated by my mouse.

It seems to be fixing it. I will keep you informed.
