I'd hope he'd have found it after 3 weeks....and you'd better double check the Tracking Bar being in the Customize list...I don't see it as a choice at all in NX3 or NX4. I could very well be doing something incorrectly, but I've never known the Tracking Bar to be part of the toolbar Customization list.
I wasn't really looking for anything...just not sure what gave cyberpete the idea that the tracking bar is shown on the MB3 -> Customize list of toolbars....his post could be misinforming other readers.
