defeating RR's startup oddities

[Dr.John R.Vokey]

Metacarders,
   I sent a stack to a colleague who uses RR rather than mc to run an 
experiment.  On preopenstack, the stack does the usual to prevent the 
experimental participants from clicking menus or background with 
untoward effects:

on preopenstack
   hide menubar
   set the decorations of this stack to empty
   set the backdrop to black
end preopenstack

In Metacard, things work as they should when the stack is dbl-clicked 
(and mc not open).  In RR, in contrast, all the usual palettes open, 
*then* the script above is executed, and then the stack itself 
disappears from the screen.  Is there some preference (or command) in 
RR that will defeat this unconscionable behaviour?
