Meanwhile, back at the ranch, my problem seemed to be a compiling  
issue. I could use some clarification.

Moved a script from a 10.5 to a 10.6 machine. Contained a line like:

splittext foo using return

Opened the script and got the <event blah blah..>. version.  Oops.   
Forgot to put Satimage in the ScriptingAdditions folder.  Put it in  
and reopened the script and now the command compiles, but running the  
script generates an error:

"(big bunch of text) doesn't understand the splittext message."

Restarted computer. Same result.

So I delete

splittext foo using return

and type in

splittext foo using return

Compile. Run. Presto. It works.

What happened there?
