Brian:

Thanks, I'm obviously still learning.  What I meant by parameters of movement of manipulation tools was the amount of change seen on the workspace for a given movement of the mouse when a tool for manipulation of the selected object is chosen.  Generally the main camera is moving and it can either pan gracefully and slowly around the object, or it can jump a large distance for a small movement of the mouse.

I was unaware of the scene magnitude setting - I'll have to play around with it.

Thanks again.
