I'm using R with emacs & ESS on Windows. When I create a plot, sometimes R
will seem to get stuck in a busy loop, i.e. it will use 100% of my CPU.
However the system is still somewhat responsive, and the problem usually
goes away if I create a new device with windows(). If I then close this
device, making the first device active again, sometimes R will get stuck in
the busy loop again.

Has anybody heard of this behavior, or, better yet, have a solution?

Thanks,
Jonathan
