I had originally set DT to use the scripts in a folder on my Dropbox. However, I had to relocate my Dropbox recently to another drive, but DT still references the old location (old drive).
I may get struck down by lightning for suggesting this but… What would be the risk or potential consequence of placing smart rules in a Dropbox folder and then using a SymLink or Alias in the ~Library/Application Scripts folder?
If smart rules are synced to multiple computers but only one computer changes them at a time, what is the potential adverse effect that you are trying to avoid?
