I didn't think so. I saw nothing to that effect (other than the
kDRMacIconLocation).

Ok, that's what I was guessing was the reason for it.

Can't do 1, but doing 3 via 2 seems like my best bet.  I did wonder if there
was a way to "clear" the position so that the Finder/OS would just pick the
best position... and if 0,0's the way to go, great! :-)

Yes. The app I'm working on searches for files/folders on disk. You get the
results in a flat table, then you can select items and burn them to disc. So
this is really only a top-level problem.

However, since folders can be burned well... if the contents in there is of
a particular layout, at least it'll match the way it was on their machine.

I will give this a try.

Thank you much for your informative and helpful reply.
