Got the load script command working now.
Took out all the things that could complicate matters, like the
version number on the script name.
Added the invisible file extension ... out of sight, out of mind.
Tried it in the Applications folder... it worked; tried it in the
Photoshop folder... it worked; Settings folder ... success again;
Scripts folder ... happy days!
But the next sub-folder was a folder too far.
So in the Scripts folder it shall reside!
Thanks again for your help
