Can a script parameter be used on first window open start up?
I can't seem to find the same window --like when I create a button with a script parameter.
I believe there's no way to add the parameter the 'normal' way in the script trigger dialog of File Options.
Most people just make a script that is only run onFirstWindowOpen, so there's no need to have a parameter.
You could make this onOpen script perform the script you want to run at this time and pass the parameter that way.
Perform script . <<yourScript>> parameter <<yourParameter>>
