That is the same here.  It is because of the -np (no pause) option
available with -dev xwin.

That is the same here.  I have forgotten the details, but I believe
the "Lena" example necessarily must turn off the no-pause option
internally in order to work at all.  So
you have to hit return to get through it.  After that example, (see
examples/tcl/standard_examples.tcl.in) plpause 0 is executed (
http://plplot.sourceforge.net/docbook-manual/plplot-html-5.9.9/plspause.html)
to disable pausing again.

that my problems might also be shared by other OS X users and maybe we
haven't had bug reports because OS X is a "minority OS" wrt PLplot and
usage is light, or actual Tcl users are doing something that I don't
know how to do.

No, your above test results indicate all is perfect with
Tcl and -dev xwin on your system, and your prior test
indicated all was perfect with Tcl and -dev psc on your system.
