OpenOffice focus

I have a tiled workspace with a WFrame named 'Aux' and the following
'Aux' kludges:

defwinprop{
   class = "OpenOffice.org 2.4",
   target = "Aux",
}

defwinprop{
   class = "Acroread",
   instance = "acroread",
   acrobatic = true,
   target = "Aux",
}

Both Acrobat and OpenOffice open in the 'Aux' frame as desired,
but starting OpenOffice moves focus to the 'Aux' frame.  Acrobat
does not change the focus.  Changing switchto from true to false
doesn't seem to change this behavior.

Is there a way to configure ion so that OpenOffice leaves the focus
alone the way Acrobat does?
