What I learned from the previous disccussion is that there is no
alternative, unless changing the behavior of CLIM on this platform were
considered an alternative. (E.g., chuck passive highlighting and have
the usual mac 1-click to select, double-click to act, where these would
apply the innermost presentation. Then you could use event-driven
processing to have multiple windows active without multiple processes.
Of course behavior that differs to this degree is problematic in terms
of portability and what it means to have a Clim "standard".)

Great! Thanks to both of you ...

The FAQ should go into the documentation, in a well-indexed chapter on
programming idioms for things people often want to do.
