Ok, if you want the default to be saved between restarts, you need to save the default path somewhere, and LabVIEW's *.ini file is a good place for stuff like this. Use the configuration file vis to read the default path the first time the browser executes (the path in the shift register will be an empty path) and write the path back to the configuration file if the user changes it.
Things get a little more complex if you are going to be distributing your code as a standalone executable, because then you have to keep track of which *ini file to use: LabVIEW's or the standalone application's.
I'l put something together and post it tomorrow...
