I am fairly new to Navisworks, though an old hack at Revit.
I have been delving into Navisworks only to find that my preferred method of navigation (Middle-click-pan, Shift-middle-click-orbit, middle-wheel-zoom) is fraught with issues. I am finding that at times, there is no response. The view cube goes dead, and the steering wheels don't work?
I have experienced this on several machines with different configurations, with both NWM2012, NWM2013 and NWS2013.
Is there something that I am missing? This is making the soft ware unusable....
