InRoads Roadway Designer settings

I'm having a bit of trouble on my new machine at work.  My scroll wheel on my mouse does not zoom in/out  in the cross section view of the roadway designer.  The scroll wheel acts just like hitting the up or down arrow on the scroll bar to the far right.  clicking the mouse wheel in also does not pan around like it used to.  My buttons work and are set correctly in Microstation after I remapped all my button assignments, but they still don't work correctly in the roadway designer.   Is there somewhere I can set these things?, or is there settings i'm not aware of?   

any help would be appreciated,
