Here is some code found (I think) in the tutorial. I haven't tried it but if I'm not
mistaken the version of the SDK I am using is 3.0 (I'm new-ish, so I could be wrong
;). It is
likely what you are doing (and if so I don't know what the problem is) but here it is
anyways :)

* FUNCTION: ProtectOurDatabase
*
* DESCRIPTION: Sets the bit in the database header which tells the
* launcher that this app shouldn't be beamable.
*
* Note that this function assumes we're the active UI app.
* (See note in the code for what to do if you're not.)
*
* Once this routine has been run, the launcher will not
* allow this app to be beamed. You can call this routine
* as many times as you want; calling it when the app is
* launched is convenient and won't slow down the rest of
* the OS by wasting time during the other launch codes.
*
* Setting this bit at compile-time would be better, but
* none of the current tools allow this yet. When they
* do, you can get rid of this routine.
