I have created a script that calls an Applescript that talks to Keynote.  Using Filemaker's Applescript calculation dialog, when I update the external applescript, Filemaker does not pick up the changes.  I'm running 12.0 v5 Advanced.  The trial version of FM14 exhibits the same behavior.  I've tried renaming the external file, restarting the Applescript editor, restarting Filemaker, and restarting the machine. Here is the script step:

"set scriptPath to \"Primus:Users:Curtis:Documents:AppleScripts:ShowDeal.scpt\"" & ¶ &
"set loader to load script alias scriptPath" & ¶ &
"tell loader to showHand(" & Quote($Presentation) & "," & Quote($Player) & ","  & Quote($Cards) & ")"

To troubleshoot another issue (no Applescript debugger), I inserted a Display Dialog command, which I later took out.  When Filemaker runs the script, the dialog displays.  The script does mostly does what it is supposed to do, but I would like to know the cause of this behavior.

The problem was in Keynote.  I restored it from Time Machine and everything sings now.
