Persistent - CS 5.5 and userInteractionLevel = NEVER_INTERACT (is it possible)?

#target InDesign 

#targetengine "session"

app.scriptPreferences.userInteractionLevel = 1699640946; //NEVER_INTERACT;

I've even tried to wrap this into a floating persistent dialog box script that runs, and for example "missing fonts" still pops up. But running it in a run-once script it will suppress the dialog box.

We need never to see any of the dialog boxes (period) they just get in the way in our workflow... and AutoHotkey; etc. script catching the window title and hitting "Ok" is proving to be too slow...

Any help would be literally amazing! Thanks!
