I was not the first user of this copy of Civil 3D 2010 and it seems the function of the mouse wheel has been reassigned to something having to do with coordinate tracking?  How do I get it back to the "PAN" function when you push the mouse wheel and drag?  The help explanation goes into CUI and something about macros.  I just want it back to the default setting. Thanks in advance for any help. Chris

Thank you John Conner;That MBUTTONPAN variable was the culprit!  That solves one of my major frustrations; now I can go back to the easy pan method instead of having to type "P" and then exit out of the command each time. That should be a big time saver.Chris
