Desktop.el isn't a very satisfactory solution because of flickering.
The GNU Emacs initial frame shows up in a certain place and position and
then resizes and move somewhere else.  But maybe the registry --- which
you mentioned below --- would be a nice solution.

Thanks.  I will check that.

You're totally right.  That has always been my experience too, but it
evidently didn't change my bad habits yet. :-)
