Keeping `knitr` from popping up plot windows

Question

I'm switching from Sweave to knitr and like it very much. Big THANKS to Yihui!

One thing that keeps annoying me is that plot windows pop up and get active. So when I write while knitr is working, my editor looses focus every so often. This happens even if there's no plot produced in the code chunk.

Is there a way to avoid this?

Here's my sessionInfo (), in case that helps:

This must have been fixed in a commit last week. There will not be plot windows opened any more. If you do not know how to install the development version, you will wait for about one week for the next CRAN release, otherwise just install from Github.
