Applescript prompting user to save only on some computers

Question

I have an applescript that does some workflow on some images. One some computers, the script completes just fine (opens a RAW file and saves a JPG), on others, Photoshop is prompting the user w/ the Save dialog box instead of just saving and closing the document. Is there a preference I'm missing that forces that save dialog box to always show instead of just proceeding with the script?
Save script snippet
open thePhoto as Camera RAW with options {class:Camera RAW open options, bits per channel:eight}
set myJPGPath to dropLocation & nameWithoutExtension & ".jpg"
set myOptions to {class:JPEG save options, embed color profile:true, format options:progressive, quality:12, scans:3}
save current document in file myJPGPath as JPEG with options myOptions appending no extension without copying
close document 1 saving no

Have a look in the dictionnary for preferences (script preference): "user interaction level.
You can check on each station for this property and be sure it's the source of the problem.
I had this problem because i had some script that was setting it to "never interact" (in a batch, you dont want to handle "link missing dialog by exemple) but was not setting it back to "interact with all" (wich can be a problem depending of the scenario you are handling).
