I missed this when it first came around, but you may be interested to know
that If you try to run MultiFinder 1.0 and System 4.2 with _Finder 5.5_ it
will work properly- except for the bug you just described.

I wonder what Apple is doing in the current Finder that breaks all the rules?
How about tail-patching various file system traps?

It might be amusing to run really old Finders (1.1g, maybe) with MultiFinder
and see just how long they last before dying. (Maybe not too amusing,
especially if they take your hard disk with them...)
