I emailed you the my suggestions below
"I tried running LabVIEW 6.1 on a Linux machine here running red hat
7.2 and I couldnt reproduce you issue. I got the full pathname
'/home/login_name/untitled1.vi. I even tried LabVIEW 7 and that
worked fine too. This maybe a silly question but I just want to make
sure we have
everything covered. Did you stretch the path indicator so that you
are seeing the complete path?
If you are just concerned about the '/', then what you can do is
convert the path to string, remove the '/' from the string and finally
convert the string back to path.
These VIs are located at Functions >> Strings >> String/Array/Path
