[InstallNDA doesn't work from an NDA under 5.0+]

This actually isn't a bug--it's a side-effect of some changes made in
the desk manager to avoid potential re-entrancy problems.

The solution is to use SchAddTask (see Scheduler chapter of TB Ref Volume
2) to schedule a call to a procedure that calls InstallNDA.  The call
will happen when the BUSY flag gets down to zero, at which point the
Desk Manager's data structures will be available for InstallNDA to
modify.

(This tip will appear in a March 1990 Technical Note.)
