Although, as regular readers know, I'm very opposed to the 'blame Apple
for everything' school of developers, I believe THINK is right in calling
this a bug.

MultiFinder is supposed to maintain separate trap patches for each

you don't want to swap the patches in before you swap the corresponding
value of CurrentA5.
