Is this unacceptable behavior confined to OS 8.x?  To some specific Mac
models?

In our situation, we have a student lab with a mix of 6100's and
7600's.  Mathematica -- front end and kernel -- runs on the individual
machines networked to a server.  But these machines are networked via
AppleTalk to a Unix server where our own notebooks reside.  Due to
security software, it is impossible for users to temporarily disable the
AppleTalk network.

Right now we still have Mathematica 3.0.1 installed in that lab.  If the
cited problem affects our configuration, then version 4.0 will be
USELESS to us!!!  (And what's worse, faculty users will have upgraded to
4.0 on their own machines and quite possibly prepare notebooks
containing, e.g., nested cells, that cannot be understood by the 3.0.1
front end, or give instructions such as using the real-time 3D graphics
manipulation that does not exist in 3.0.1.  In short, a total disaster.)
