Are you having trouble with calling CloseDeskAcc? You would have to be carefull
to make sure that after calling CloseDeskAcc your code did nothing that could
disturb memory sinse you are now operating out in either unlocked or purgable
code. If CloseDeskAcc is moving the code befor you return (run your code with
Heap Scrample turned on in MacsBug to test things out) then you could try to
chain to CloseDeskAcc. To do this call GetTrapAddress to get the address of 
CloseDeskAcc push your parameter and the ruturn address of the routine you are
in and jump to CloseDeskAcc. I hope these ideas help.
