See the posting guide. NEWS in R-patched says
? In R 3.0.0, identify() and locator() did not record information
correctly, so replaying a graph (e.g. by copying it to another
device) would fail. (PR#15271)
If your device does not use backing store (mine does) then minimizing
and replaying will replay the display list.
