Set style of first window

[Xetabase]

Filemaker 12 lets you set the style of new windows that are created by a script, so you can disable things like scrolling, zoom, maximizing, etc. But how do you set these options on the FIRST window that opens when the database file is launched?

You can't. I make an OnFirstWindowOpen script that opens a new window and immediately closes the first window

I wonder if there is a way to hack the database file to modify the default window style?
