And just to add a note to the discussion. Marc added to the Mac version of LabVIEW the standard ability to see and move to the entire path hierarchy by right-clicking (control-clicking) the window title bar. This is a standard for the finder and most applications under Mac OS X and was a great feature to add to LV.
It works on either the FP or BD in edit mode and just the BD in run mode. This little touch has made using LV much much nicer. And I don't have to find the tools menu either!
I think it appeared in LV 8.2 (maybe 8.0, all those versions run together).
Cheers!
