this was done for production time considerations. Not that we intentionally
programmed it this way. It's just that there was a lot to do when programming
the Finder, a routine was hammered out that worked, and it stayed that way
because *it worked*. The big maxim around here is that if it isn't broke,
don't fix it. And I think that everyone would agree that there are plenty of
things that ARE broken that SHOULD be fixed. It would be nice to change the 
algorithm, but there are always other pressing matters (like adding AppleShare 
support under GS/OS). When the new Finder comes out on the 4.1 system disks, I 
think that you will be pleased with the new features!
