Thanks for your suggestion. This does almost everything I want. Two small=20
drawbacks:

1) Setting par(bg=3D...) from the hook has no effect for the first graph pl=
otted=20
in the new device. For this to work, the hook would need to be called=20
before .Internal(plot.new()) instead of afterwards in plot.new().

2) Any par() parameters explicitely set in the call to X11()/postscript()..=
=2E=20
will be overridded, instead of taking precendence over the defaults.

=46or many purposes this method is really useful, however, so thanks again =
for=20
pointing it out.

Regards
Thomas
