According to tech note MG592338, "xDX Designer does not allow relative paths for the netlist.prp file."
All other paths in xDX Designer > Setup > Settings > Project are allowed to be relative except for the Property Definitions.
Is there a reason for this? Because only absolute paths are allowed, when passing projects back and forth between team members, this netlist.prp file location must be constantly updated in the Settings window. Why can't this use a relative path like the other files in the Settings window?
