That works for me. Very awesome.  Most appreciated.

I've just tried the following in 2.6.2

auk% cat x11.R
X11()
interactive()
plot(1:10)
locator()
q()

explicitly launch a device.  It seems to be responsive enough (at least
on my system) and will stay up until you middle- or right-click on the
device surface.  In earlier threads others have reported some problems
with this approach, but see how it works for you.
