R help - Mar 2007 - CPU usage on Windows

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

I've heard of a number of problems with Emacs on Windows.  I wouldn't 
recommend using it.  As far as I can see, it makes a number of 
assumptions about the OS that just aren't true about Windows.

If you can reproduce the behaviour outside of Emacs, I'll investigate.
