Now we have to reset all preferences etc...My 1st problem is getting the middle "mouse wheel" to act as a zoom without using another button...right now we use the left mouse button and the shift key to get mouse zooming, but it is really different from what the other guys and myself are used to...I did get pan re-associated with holding down the wheel. thanks for your time.
