Yes, thank you, this fixes the problem for me.

As a follow-up, and again with my ignorance of where processing is actually occuring, it seems like the X11 window content is drawn directly rather than being drawn to a buffer and then blit on to the screen -- the original appearance of the plot is slow, compared to, e.g., hiding and then revealing the image once it has been plotted.

R version 2.8.0 Under development (unstable) (2008-04-05 r45102)

Thank you again for tracking down the original issue.
