Thanks for the responses, chaps,

I tried Mark's

load script POSIX file "Macintosh HD:Applications:Adobe Photoshop  
CS3:Presets:Scripts:Applescripts:BackToIndyV1.2"

and got

Can’t make POSIX file "Macintosh HD:Applications:Adobe Photoshop  
CS3:Presets:Scripts:BackToIndyV1.2" into type file

I tried John's

load script alias...

and got

Can’t get alias "Macintosh HD:Applications:Adobe Photoshop  
CS3:Presets:Scripts:BackToIndyV1.2".

... and it's there because I'm looking at it.

Tried shortening the path  by dropping the file into the apps folder,   
but still got no joy.

It's brick wallsville here at the moment!
